what impulse occurs when an average force of 10n is exerted on a cart of 2.5 s? What change in momentumdoes the cart undergo/ If the mass of the cart is 2K and the cart is initally at rest, calculate it's final speed.

A mass M = 0.464 kg moves with an initial speed v = 2.98 m/s on a level frictionless air track. The mass is initially a distance D = 0.250 m away from a spring with k = 844 N/m, which is mounted rigidly at one end of the air track. The mass compresses the spring a maximum ...

A 10.0 kg cart and a 15 kg cart are locked together with a compressed spring between them. They are then released so that the spring pushes the two carts apart. The 15 kg cart is moving at 3.0 m/s afterward. How fast is the 10.0 kg cart moving?
