The horizontal coordinates of a Frisbeetm in a strong wind are given by x=−12t+4t2 and y=10t−3t2, where x and y are in meters, and t is in seconds. (a) What is the acceleration of the Frisbee? Give a magnitude.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
