A car goes round a right-angled corner so that its velocity changes from 12 m/s due east to 16 m/s due south. What is the change in velocity?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
