A special airport truck is used to push a heavy airliner away from the terminal. The truck pushes with a force of 4250 N for a distance of 210 m. Calculate the mechanical work done by the truck.

If a simple machine reduces the strength of a force, what must be increased?

The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
