A ball of mass 2.00 kg, resting on a horizontal frictionless surface, gets hit by another ball of mass 1.50 kg moving in the +x-direction with a speed 4.00 m/s. After the collision, the 1.50 kg ball has a speed of 2.00 m/s at an angle 60.0° counterclockwise from the +x-direction.

a) Find the velocity of the 2.00 kg ball just after the collision. Express your answer in vector form.
b) Compute the percent of kinetic energy lost in the collision.

A mass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. It takes 3.7 J of work to compress the spring by 0.14 m . If the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of 12 m/s2. Find the value of the spring constant. Find the value of the mass.

The diagram below shows a block of mass m = 2.00 kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1 = 4.00 N, F 2 = 6.00 N, and F 3 = 8.00 N are applied to the block, initially at rest on the surface, at angles shown on the diagram. In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles...
