... push, the 100 kg person is moving A. Twice as fast as the 50 kg person B. The same speed as the 50 kg person C. Half as fast as the 50 kg person Equal and opposite forces, but a=F/m. so the accel of 100 kg person is half that of 50 kg person. Accel is applied for same time, and v=at. Or… by conserva ...

Circular motion
... An object that moves in a circle is accelerating even if its speed is constant. For an object undergoing uniform circular motion, the magnitude of the velocity (speed) remains constant, but the direction of the velocity is continually changing. Since acceleration is defined as the rate of change i ...
