A 3000-kg truck moving with a velocity of 10 m/s hits a 1000-kg parked car after which they stick together.  Determine their velocity immediately following the collision.

Block A (m=2.5kg) and Block B(m=3.5 kg, to the right of A) move on a frictionless horizontal surface. Initially, Blocl A is moving to the right st 6 m/s and Block B moves to the left with unknown speed. They collide head-on in a perfectly elastic collision. After the collision, block B moves to the right with a speed of 4.5 m/s. A) Find the speed of block B before the collision B)What is the velocity (magnitude and direction) of block A after collision?

A west bound 1500 kg car moving at 13.0 m/s collide with a north bound 2500 kg car moving at 20.0 m/s. Ifthe cars stick together after collision, calculate the magnitude and direction of their common velocity.

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 135 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

Consider a 935 kg car initially moving at 30.5 m/s.  a) what is the velocity of the car, in meters per second, just after it hits a 140-kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car.

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 125 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

A 200,000 kg railroad car moving at 3.00 m/s couples up with (sticks together) with another 150,000 kg car at rest.  What is the final speed of the two cars immediately after the collision?

A two-stage rocket moves in space at a constant velocity of +4470 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1250-kg upper stage is +5950 m/s. What is the velocity (magnitude and direction) of the 2450-kg lower stage immediately after the explosion?

Two carts are involved in an elastic, head on collision. Cart A has a mass of mA = 1.5mB, and initial velocity of vAi = 4.5 m/sto the right. Cart B has an initial velocity of vBi = 0m/s and a final velocity ofvBf = 2m/sto the right after the collision. a) What is the final velocity of cart A? b) What is the mass of cart B?

A two-stage rocket moves in space at a constant velocity of +4570 m/s. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 1060-kg upper stage is +5750 m/s. What is the velocity (magnitude and direction) of the 2250-kg lower stage immediately after the explosion?
