A skydiver is falling at constant velocity. If a force of 600 N is pulling down on the skydiver, how much force must be acting upward on the skydiver? exactly 600 N slightly more than 600 N slightly less than 600 N exactly 0 N

Fredo's spaceship takes him to the very edge of known space. There, gravity has no effect at all. Fredo takes a baseball and tosses it into space. What will most likely happen to the ball?

A 26-g steel-jacketed bullet is fired with a velocity of 630 m/s toward a steel plate and ricochets along path CD with a velocity 500 m/s.

A small boat is carrying four people across a river. Without any paddling, the boat moves downstream at a steady speed of 5 m/s. If the average weight of the four people is 60 kg, then what is the speed of the boat after one person gets?

Does temperature affect the dissolving phase?

In a clear, coherent, paragraph-length answer, explain why the speed of the apple half way between the release and the maximum height is not half the initial speed.
