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.)

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
