Levi and Clara are trying to move a very heavy box. Levi is pushing the box with a force of 30 N, and Clara is pulling the box with a force of 50 N. The box exerts a frictional force of 65 N.

Calculate the amount of work done if you use a 100 N force to push a 50 kg box 5 m across the kitchen floor.

A 50 kg bicyclist, traveling at a speed of 12 m/s, applies the brakes, slowing her speed to 3 m/s. A) How much work did the brakes do? B) If the net force slowing her down is 120 N, over what distance did this take place?

explain how a maglev train provides evidence that magnetic fields can apply forces between objects that do not touch.

Two rocks are moving through empty space in a straight line at the same speed. One has a mass of 10 kg, the other has a mass of 50 kg. Which statement about the rocks is true? A. Both will be stopped by the same amount of force acting against them.

A girl throws a rock horizontally, with a velocity of 10 m/s, from a bridge. It falls 20 m to the water below. How far does the rock travel horizontally before striking the water?

As you throw a ball, you exert a force on that ball of 4.2 N. You exert this force on the ball while the ball moves a distance of 0.50 m. The ball then leaves your hand and travels a horizontal distance of 8.5 m to your friend.

How does folding change rock layers

Why is mass movement more common after a heavy rainfall?
