As a skydiver with a mass of 54 kg falls toward the Earth, she accelerates at 9.8 m/s2. What is the force of

gravity acting upon the skydiver? What must be true about the force of air resistance acting on the skydiver?

Up, down, and forward are examples of relative directions. North, south, east, and west are directions, which are indicated by a compass rose on a map.

Why does a skydiver accelerate as she falls to the earth before opening her chute?

What is the magnitude of 20 kg and 0.5m/s

Consider a 77.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.08 m/s in 0.900 s. It travels with this constant speed for the next 5.00 s.

Recoil is noticeable if we throw a heavy ball while standing on a skateboard. If instead we go through the throwing motion but hold onto the ball, without friction effects our net recoil will be A) zero. B) the same as before.

If an electromagnet is used to pick up nails and other metal objects, what happens when the current is turned off?

An electron enters a region of uniform perpendicular en and bn fields. it is observed that thevelocity nv of the electron is unaffected. a possible explanation is:
