The magnitude of momentum change isConservation of linear momentum in a collision follows directly fromA force F acts on a 2 kg body for 3 s, changing its speed from 2 m/s to 8 m/s along the line of F. The magnituThe maximum static friction force on a body is f = μN. Static friction is best described asA 10 kg block on a frictionless surface is pulled by 20 N horizontally and 20 N at 60° above horizontal. The hImpulse equalsA body in equilibrium under several forces hasA 0.5 kg ball hits a wall at 10 m/s and rebounds at 10 m/s. The impulse on the ball isNewton's second law in vector form isA lift accelerates upward at 2 m/s². The apparent weight of a 50 kg person (g=10) isTwo blocks of 2 kg and 3 kg connected by a string are pulled by 10 N on the 3 kg block (frictionless). The accThe SI unit of force, the newton, equals
