A 1200 kg racecar is traveling at 175m/s is slowed to a stop. What is the force required to stop the car in a distance of 120m?

Missy Diwater, the former platform diver for the ringling brothers circus had a kinetic energy of 15,000 joules just prior to hitting the bucket of water. If missy's mass is 50kg, the what was her velocity.

Which device for controlling lift allows air to flow from the lower surface to the upper surface at high angles of attack?

Your car has stalled and you need to push it. You notice as the car gets going that you need less and less force to keep it going. Suppose that for the first 15 m your force decreased at a constant rate from 210 N to 45 N.

What distance was an object moved by a force of 40 N if the work was 600 joules

Do you think Pluto should be considered a planet? Why or why not?

An object starts from rest at time t = 0.00 s and moves in the + x direction with constant acceleration. The object travels 14.0 m from time t = 1.00 s to time t = 2.00 s. What is the acceleration of the object? a) 5.20 m/s^2 b) 10.4 m/s^2 c) 8.

A box is dragged without acceleration in a straight-line path across a level surface by a force of 13 N. What is the frictional force between the box and the surface?
