The same two carts are initially at rest touching each other. A compressed spring between them is released and the 1500 g cart takes off toward the right with a speed of 25 cm/s. How fast and in what direction does the 500 g cart move? Ignore the mass and motion of the spring.

Suppose that two carts, with a compressed spring between them (but not attached to either cart), are free to roll on a level table. The carts have very different masses and are initially stationary. Consider frictional losses to be negligible. The spring is released and the carts move apart. Are the final kinetic energies of the two carts equal, or is one greater than the other (if so, specify which is greater)? Explain your reasoning using fundamental physics principles, laws,...

1. A 30 cm spring with constant 70 N/m is compressed to 10 cm and placed between two carts. Cart A has mass m Skg and mg is unknown. Initially the system is at rest. After it is released it is observed that cart A has three times the velocity of cart B. a) What force must be exerted initially to keep the spring compressed? b) What is the work done to compress the spring? c) By considering conservation of...

Two blocks on a frictionless table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring has a spring constant of 215N / m and was compressed by 0.20 m. If one of the blocks moves at 1.50 m/s and the other moves away at 3.00 m/s , what is the mass of the heavier block in kg? (Hint: mechanical energy in...

A 0.19 kg mass is held at rest against a compressed spring with a spring constant of 103 N/m. When released, the mass leaves the spring with a speed of 6.28 m/s. Assuming that the spring force if wholly responsible for changing the motion of the mass, by what distance was the spring initially compressed from its equilibrium position?

Two air track carts move along an air track towards each other. Cart A has a mass of 450 g and moves toward the right with a speed of 0.850 m/s. Cart B has a mass of 270 g and moves toward the left with a speed of 1.12 m/s. What is the total momentum of the two-cart system? Give your answer in kg m/s, to three significant firgures.

Two blocks on a friction less table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring has a spring constant of 215 N/m. One of the blocks moves away at 0.45 m/s while the other moves away at 0.90 m/s. The heavier of the two blocks has a mass of 1.4 kg. How far was the spring compressed in m?

Two carts are sitting on air track (frictionless surface). Assume cart A has mass of .50 kg, cart B has mass of 1.0 kg. You push cart A and give it an initial speed of 5.0 m/s toward B which was originally at rest. The two carts stick together and move together. Right after collision, the air is turned off so the two carts slide to a stop due to kinetic friction. Assume the coefficient of kinetic friction is .20....

Carts A and B move directly toward each other and collide perfectly elastically. They move off from the collision directly away from each other. The mass of B is N times the mass of A. Before the collision, A is moving toward B at a speed of vo; after the collision, B is at rest, and A moves off at a speed of -Vf. Calculate the speed of cart B before the collision. NOTES: Enter an algebraic expression. Be sure...

A ball of mass m is pushed out by a compressed spring of spring
constant k. Both the ball and the spring are on a table (see the
diagram below). The other end of the spring is fixed to the table,
and the spring is initially compressed by x. The ball moves toward
a wedge at the edge of the table and then launches off the wedge
and falls on the ground. The heights of the table and the wedge...
