A volleyball is spiked so that it has an initial velocity of 14 m/s directed downward at an angle of 60° below the horizontal. What is the horizontal component of the ball's velocity when the o
A 14.0-kg box is being pushed from the bottom to the top of a frictionless ramp. When the box is pushed at a constant velocity, the nonconservative pushing force does 58.0 J of work.
A bumper car with mass m1 = 107 kg is moving to the right with a velocity of v1 = 4.6 m/s. A second bumper car with mass m2 = 99 kg is moving to the left with a velocity of v2 = -3.5 m/s. The two c
