... Example: rolling ball How fast will a ball be going at the base of a ramp if it is released at the top of the ramp, where the length of the ramp is 2 meters and the high end is 50 cm above the floor (base of the ramp)? We assume the ball rolls without slipping. Does the mass or radius of the ball a ...

How do we figure out net force? • Similar to any other time, when an object is on an inclined plane, we must combine all the forces acting on it to find the resulting net force. • There are three general cases we encounter: – When the object is at rest. – When the object is moving at a constant vel ...
