• The ball would not roll up the other plane at all.

• to nearly twice the original height.

• to nearly the original height

• to nearly half it is original height

An object following a straight-line path at a constant speed

• has zero acceleration

• has no forces acting on it

• has a net force acting in the direction of motion

• none of these

You push on a car and it does not move. What is true about the inertia?

• The inertia is changing

• The inertia of the person is equal to the car

• The inertia of the car is too great

• There is not inertia because of no movement
