A railcar of mass (m) is moving at speed (v) when it collides with another railcar of mass (M) which is at rest. The two cars lock together and roll on the track. A. What is the speed of the cars immediately after the collision? B Is this an example of an elastic or inelastic collision? Explain

You are standing at a stop light waiting to cross the street when you witness a collision. A 2,300 kg Ford F150 truck collides head on with a 1,300 kg Toyota Corolla. The Ford F150 is moving to the right immediately before the collision and the Corolla is initially moving to the left. The two vehicles have the same initial speed and vehicles stick together after the collision. A. What type of collision is this? B. Which vehicle will experience the greater change in momentum? C. Which vehicle will experience the greater acceleration?

The figure below shows a bullet of mass 230g traveling horizontally towards the east with a speed of 415m/s, which strikes a block of mass 7.5kg that is initially at rest on a frictionless table. After striking the block, the bullet is embedded in the block and they begin to move as one unit.  A. What is the magnitude (in m/s) and direction of the velocity of the block/bullet unit immediately after the impact? B. What is the magnitude (in N * s) and direction of the of the impulse of the block on the bullet?  C. What is the magnitude ( in N *s) and direction of the impulse of the bullet and the block?

A system composed of the following particles: a 0.500 kg particle at the origin; a 1.25 kgkg particle at x = 0.150 mm, y = 0.200 mm; and a 0.750 kg particle at x = 0.200 mm, y = -0.800 mm. a.  Find the x-coordinate of the center of mass of the system. b. Find the y-coordinate of the center of mass of the system.
