1. consider the falling and rolling motion of the ball in the following two resistance-free situations. in one
situation, the ball falls off the top of the platform to the floor. in the other situation, the ball rolls from
the top of the platform along the staircase-like pathway to the floor. for each situation, indicate what
types of forces are doing work upon the ball. indicate whether the energy of the ball is conserved and
explain why. finally, fill in the blanks for the 2-kg ball.

A clock is constructed using a regular polygon with 60 sides. The polygon rotates every minute. The clock has already rotated for 7 times because each rotation of the clock is equal to 1 minute. In a clock, it has a total of 60 minutes. After 60 minutes, that is equivalent to 1 hour.

So the clock has rotated for 7 times.
