POESR A science student is riding on a flatcar of a train traveling along a strait, horizontal track at a constant speed of 15 m/s. The student throws a ball into the air along a path he judges to make an initial angle of 67° with the horizontal (toward the rear of the car) and to be in line with the track. The student's professor, who is standing on the ground nearby, observes the ball to rise vertically. With what initial speed does the professor see the ball rise? 10. 38.14 m/s D. 36.74_m/s 33_m/s 35.34 m/s E. 31.39 m/s F. 34.16 m/s A. B. C.

If a projectile is fired from the origin of the coordinate system with an initial velocity υ0 and in a direction making an angle α with the horizontal, calculate the time required for the projectile to cross a line passing through the origin and making an angle β < α with the horizontal.
At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of vi=(3.00i2.00j)m/s and is at the origin. At t = 3.00 s, the particles velocity is vf=(9.00i+7.00j)m/s. Find (a) the acceleration of the particle and (b) its coordinates at any time t.

A bullet is fired from the ground with an initial velocity of 50 m/s that makes with the horizontal an angle of 30°. The y-component of the velocity (v,) of this object after 1 second is?
A batter hits the baseball A with an initial velocity of vo-98 ft/sec directly toward fielder B at an angle of 36° to the horizontal; the initial position of the ball is 4.0 ft above ground level. Fielder Brequires 0.49 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the "catch position" simultaneously with the baseball. The catch position is the field location at which the ball altitude is 8.3 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made. Answer: VA 242" i+ i) ft/sec
A parent at a Little League game returns a foul ball by throwing it back onto the field. When the parent throws the ball back, she is standing and ends up releasing the ball from a point that is 2.50m above the ground. Your best guess is that she threw the ball upward at an angle of 60o with respect to the ground and it landed 13m away from her. What was the height of the ball's apex (as measured from the ground)?
In a friendly neighborhood squirt gun contest a participantruns at 7.8 m>s horizontally off the back deck and fires her squirtgun in the plane of her motion but 45° above horizontal. The guncan shoot water at 11 m>s relative to the barrel, and she fires thegun 0.42 s after leaving the deck. (a) What is the initial velocityof the water particles as seen by an observer on the ground? Giveyour answer in terms of the horizontal and vertical components.(b) At the instant she fires, the gun is 1.9 m above the level ground.How far will the water travel horizontally before landing?
One strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume that both snowballs are thrown with a speed of 30.0 m/s. The first is thrown at an angle of 65.0° with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? _____° (b) How many seconds later should the second snowball be thrown after the first in order for both to arrive at the same time?
In a volleyball game held in BSU, A CE student player at position X serves the ball from a height of 1.3m from the ground, imparting it with an initial velocity at an angle of 50° from the horizontal. He aimed the all to land at point 0, 0.5m short to an Engineering Faculty player, thus making an ace, Incidentally the Engineering Faculty player is an expert in mind reading. The instant the server hits the ball, Mr Engineering Faculty started running from rest with a constant acceleration a. A. Check whether the ball will clear the 2.42m high net. (Specify the height obtained in meters) B. At what horizontal distance in meters from position Y will Mr Engineering Faculty intercept the ball, given that he intercepts it at a height of 1.6m? C. What is the acceleration in m/s^2 of Mr. Engineering Faculty? < Im net O Y 9m 9m
A firefighter d = 55.0 m away from a burning building aims a jet of water from a firehose at an angle of 8 = 51.0° above the horizontal. The water has initial speed vo= 38.0 m/s.

A projectile is launched vertically upward from the ground at the initial 3. speed vo. A second projectile located a distance L away is fired at an adjustable angle 0 at the speed 2vo toward the first projectile. If the two projectiles are fired at the same time and collide, at what angle 0 must the second projectile be fired?
A projectile is to be fired from the centre of the top of a building that is 100 m tall. It will be fired at an angle of 60o to the horizontal and at a speed of 20 ms−1 . (a) Find an expression for the position vector of the projectile at time t seconds. (b) How long it will take for the projectile to hit the ground? (c) How far away from the the centre of the building will the projectile be when it hits the ground? You may neglect air resistance and you may assume there are no cross winds etc. (Make sure you show all your working.)
