The pedals of a bicycle are mounted on a bracket whose centre is 27.5 cm above the ground. Each pedal is 17.5 cm from the bracket. Assume that the bicycle is pedalled at a rate of 10 cycles per minute. 1. Draw a graph showing the height of one of the pedals above the ground for the first 2 cycles with time in seconds. Assume that the pedal starts at the topmost position at t=0. 2. Write an equation modelling the height of the pedal as a function of time. 3. When is the pedal 15 cm above the ground for the 6th time?

A youth of mass m = 22 kg is swinging on a swing. The length from the upper bar of the swing set to the seat is L = 4.2 m. The child is attempting to swing all the way around in a full circle. a. At what minimum speed, in meters per second, must the child be moving at the top of the circular path in order to make a full circle? b. Assuming the child is traveling at the speed found in part a, what is their apparent weight, Wa in newtons, at the top of their path (At the top, the child is upside down) c. If the velocity at the bottom is the same as the velocity at the top from part a, what is the child's apparent weight, in newtons, at the very bottom of the path?
Two kids decided to play with their toys, balls. The first kid is on the ground (0.00 meter), whereas the second kid is on top of a 10.00-meter tall building. The second kid threw his ball at the same time that the first kid throws another ball upward. At the time that the first kid’s ball reaches its maximum height, the two balls will collide. i.) Compute for the initial speed of the first kid’s ball. ii.) Determine at what time and at what height the two balls will collide.

You need to guide a robot from the red dot on the left to the green dot on the right, avoiding the blue walls along the way. units To do this, you must feed it a series of commands of the form "turn degrees and move forward". Angles are measured in degrees, with positive angles turning counterclockwise, and negative angles turning clockwise. All turns are relative to the robot's current direction. The grid marks 1 unit squares. From the red starting dot, with the robot facing directly to the right, issue your commands: (all commands should be given as decimal values) Move 1: Turn 9 Move 2: Turn Move 3: Turn Move 4: Turn degrees and move degrees and move degrees and move degrees and move units forward units forward units forward units forward
