Two disks collide with the initial velocities just before the collision as shown in (Figure 1).
Learning Goal: To use the conservation of momentum and the coefficient of restitution to determine the speeds of two disks after a collision Two disks collide with the initial velocities just before the collision as shown in (Figure 1). What are the speeds of the two disks just after impact if the coefficient of restitution is e = 0.9? The masses of the disks are mA = 5 kg and mB = 7.5 kg, the initial velocities are vA = 3...

The diagram below shows a block of mass m=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00N, F2=6.00N, and F3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...
