3) Ared car of mass 1325 kg traveling east and a blue car of mass 1480 kg traveling north collide and become entangled, moving as a unit at 12.6 m/s and 57.0 north of east. Draw a diagram that shows the state of the system before and after the collision. Find the speed of each car prior to the collision. (4 points) 2) A block of mass 32.5 kg is sliding on a frictionless rail and is moving at 1.12 m/s. It collides and sticks with two blocks already stuck together, each of the same mass as the first block and moving in the same direction as the first block at 0.640 m/s. a) What is the speed of the three stuck-together blocks after the collision? (2 points) b) What is the change in kinetic energy in the collision? (2 points) 1) A 275 gblockis moving 45.0 m/s just before it strikes a 95.0 g ball at rest. After the collision, the block continues to travel in the same direction but at 38.0 m/s. Find the speed of the ball immediately after the impact. (2 points) 4) A 0.0320 kg bullet is fired vertically at 2.50 x 10% m/s into a 0.150 kg baseball that is initially at rest. How high does the combined bullet and baseball rise after the collision, assuming the bullet embed:s itself into the ball? (2 points)
