Cart 1, with m1= 5.8 kg, is moving on a frictionless linear air track at an initial speed of 1.8 m/s. It undergoes an elastic collision with an initially stationary cart 2, with m2, an unknown mass. After the collision, cart 1 continues in its original direction at 0.7 m/s. 1) The horizontal component of the momentum is conserved for cart 1. cart 2. the system of cart 1 and cart 2. Momentum is not conserved for any of these...

A pump sprays water out of a tank on a cart weighing 115 kg. The tank contains 61 kg, and the pump sprays out water at a rate of 1.95 kg/s that leaves with a speed of 2.26 m/s relative to the cart. The cart starts from rest. (a) Use conservation of momentum to find the speed of the cart after the pump has been running for 20 s. (b) What is the force on the cart at that time?

While driving down the street, your friend’s car was hit by a truck from behind.  The mass of your friend’s car is 1500 kg while the truck is 1800kg.  Your friend was driving 25 mph or 11.2 m/s. Assume that collision causes both cars to stick together and they do not supply additional power to the wheels after the collision. After the collision, the two cars slide to a stop. The coefficient of kinetic friction is 0.65 for the car and truck...

In elastic collisions,total kinetic energy and momentum are both conserved. On a frictionless track,cart 1 is moving with a constant,rightward(+) velocity of 1.0m/s.Cart 2 is also moving rightward with constant velocity of 5.0m/s.  After a while,cart 2 collides cart 1 from behind.(It is an elactic collision.)If the final velocity of cart 2 becomes 3.0m/s, what is the final velocity of cart 1?

A 1400 kg car at rest at a stop sign is rear ended by a 1860 kg truck traveling at a speed of 20.9 m/s. After the collision, the two vehicles are locked together. Alice is moving past the collision site in a frame S' that is traveling at a constant velocity of 6.69 m/s in the direction of travel of the incident truck. (a) Determine the momentum of the vehicles before the collision in Alice's frame. (b) Determine the...

In an elastic collision, a 480-kg bumper car collides directly from behind with a second, identical bumper car that is traveling in the same direction. The initial speed of the leading bumper car is 4.5 m/s and that of the trailing car is 7.2 m/s. Hint Assuming that the mass of the drivers is much, much less than that of the bumper cars, what are their final speeds? The speed of the leading bumper car after collision is  m/s, and the...
