The solution is given in the attached image.
The main task was to find angle theta as shown. Rest calculation
can be done easily and hence not shown explicitly. The final
answers are boxed.

Two objects (object A and object B) are moving with constant velocities (VA=30(m/s), VB=40(m/s))&nb
Two objects (object A and object B) are moving with constant velocities (VA=30(m/s), VB=40(m/s)) in the same direction. Object B is behind object A. At the moment that the distance between them is 15(m) object A accelerates with aA = 1 (m/s^2) and object B decelerates with aB = -3(m/s). Are they going to hit each other? (show your work)

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...
