An object is projected upward from ground level at an angle (Theta) and the air resistance is negligible. If the initial velocity, v0, of the object is given in ft/sec and time t is measured in seconds, then the formulas for the object's height h and the horizontal distance traveled (the range) d after t seconds into flight are as follows. h= V0 t sin (Theta) - 16t2 d = tv0 cos (Theta) If (Theta) = 30 (Degrees) and the initial velocity is 140 ft/sec what is the following? (a) The object's maximum height. (b) The object's range.

A diver jumps off a cliff of height h at an angle θ = 260 (see figure). He reaches a maximum height of h subscript m a x end subscript= 20 m above the top of the cliff before falling to the water below. He hits the water x=295 m from the base of the cliff. Determine the height of the cliff, h. Take g=10m/s2 . Round your answer to one decimal place.

The horizontal distance or range (R) of an object thrown at an angle θ from the horizontal is represented by the equation below where v0 is the initial velocity as the object leaves the hand, in feet per second. If v0 = 2500 feet per second and θ is changed from 13° to 14°, use differentials to approximate the change in range, in feet.

To passengers in B, however, A appears to be flying sideways and moving east. Determine the magnitudes of the actual velocity of A and the velocity which A appears to have relative to B. 68
A rock is thrown directly upward with an initial velocity of 118 feet per second from a cliff 275 feet above a beach. The height of the rock above the ground h after t seconds, is given by the equation h=−16t2+118t+275. When will the rock be 446 feet above the ground? If you have more than one answer, separate them with a comma. If necessary, round to 2 decimal places.
When startled, a frog leaps from the ground 1.8 m straight up into the air. Knowing that the acceleration due to gravity is approximately 9.8 m/s² straight down, what was the frog's vertical velocity just as it left the V= ground? Don't forget units!
