6. A golf ball that weighs 0.45 N is dropped from a height of 1.0 m. Assume that the golf ball has a perfectly elastic collision with the floor.
a. In the margin, construct a motion map for the golf ball from the time it is dropped until it reaches its highest
point of rebound.
b. Determine the time required for the ball to reach the floor.
Ć What will the instantaneots momentum of the golf ball be immediately before it strikes the floor?
d. What will be the change in momentum. (Ap) from the instant before the ball collides with the floor until
the instant after it rebounds from the floor? (Illustrate with a vector diagram.)

Aman pushes on a trunk with a force of 250 newtons. the trunk does not move. how much positive work is done on the trunk? 0.0 j -250 j 250 j 125 j

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.
