This energy transformation diagram represents the energy of a boulder, initially positioned on top of a mountain. As it falls, its original gravitational potential energy is converted to kinetic energy and air friction.

A graph of velocity versus time (velocity displayed in m/s and time in seconds) displays a constant slope of 2 and a y-intercept of 4. Explain what can be inferred from the given data.

You push a shopping cart filled with groceries (total mass = 20 kg) by applying a force to the cart 30° from the horizontal. if the force you apply has a magnitude of 86 n, what is the cart's acceleration? assume negligible friction.

Two objects are made of the same material, but they have different masses and temperatures. If the objects are brought into thermal contact, which one will have the greater temperature change

A ball strikes a wall. It exerts a force of 10 N to the left against the wall and bounces off. What force does the wall exert on the ball?
