Two students stand opposite each other on the rim of the merry-go-round of 6m diameter and rotating at 12 rev/minute. One child throws a ball of mass .5kg to the other at 6m/s. Calculate the coriolis force on the ball and also how far the ball misses the other student.
The position of a particle moving along an x axis is given by x = 22t2 - 3.0t3, where x is in meters and t is in seconds. Determine the position, velocity, and acceleration of the particle
