Ball A of mass 0.55 kg has a velocity of 0.65 m/s east. It strikes a stationary ball, also of mass 0.55 kg. Ball A deflects off ball B at an angle of 37° north of A's original path. Ball B moves in a line 90° right of the final path of A. Find the momentum (in kg m/s) of Ball A after the collision.

A 2 kg disk traveling at 3.0 m/s strikes a 1.0 kg stick of length 4.0 m, that is lying flat on nearly frictionless ice. The disk strikes at the end point of the stick at a distance r=2.0 m from the stick's center. Assume the collision is inelastic and the disk adheres to the stick.The moment of inertia of the stick about its center of mass is 1.33kg*m^2. a) Does the disk have initial linear momentum? b) Does the...

A golf ball strikes a hard, smooth floor at an angle of 35.0 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0542 kg, and its speed is 41.0 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor? (Hint: Note that only the vertical component of the ball's momentum changes during impact with the floor, and ignore the...

A mass m = 17 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.06, for a distance d = 5.1 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 28° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 28° (thus on the incline it is...
