1) A 48.5-kg skater is standing at rest in front of a wall. By
pushing against the wall she propels herself backward with a
velocity of -1.46 m/s. Her hands are in contact with the wall for
1.00 s. Ignore friction and wind resistance. Find the average force
she exerts on the wall (which has the same magnitude, but opposite
direction, as the force that the wall applies to her). Note that
this force has direction, which you should indicate...

A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stops. The rocket altitude 20 s after launch is 6200 m. You can ignore any effects of air resistance. What was the rocket's acceleration during the first 16s? What is the rocket's speed as it passes through acloud 6200 m above the ground?

A test rocket is launched by accelerating it along a 200.0-m incline at 2.29 m/s2 starting from rest at point A (the figure (Figure 1) .) The incline rises at 35.0 ∘ above the horizontal, and at the instant the rocket leaves it, its engines turn off and it is subject only to gravity (air resistance can be ignored). A.) Find the maximum height above the ground that the rocket reaches. B.) Find the greatest horizontal range of the rocket...
