A 89 kg cart initially sits at rest on a flat, frictionless track. This cart of charge 0.005 C is placed in an initial potential of 939,388 V, which launches it toward a spring with a spring constant of 462 N/m. After being launched, the cart crashes into the spring that brings it to a stop. How far is the spring compressed in order to stop the cart?

    A 1.25 kg dynamics cart is launched from rest by an anchored horizontal spring that has a spring constant of 115 N/m and is initially compressed through a distance of 10.0 cm. It travels on a frictionless track until slowing to a stop at the top of a round hill. Calculate the height of the hill.

    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....

    A glider with mass m = 0.5 kg sits on a frictionless air track. It is connected to a massless spring with force constant k = 40 N/m. The glider is initially at x=0, and the spring is relaxed. You then hit the glider with a hammer, which gives it an initial velocity of υ0 = 5 m/s in the positive x direction. At what x positions will the speed of the glider be zero?

    A 2.4-kg cart is rolling along a frictionless, horizontal track towards a 1.2-kg cart that is held initially at rest. The carts are loaded with strong magnets that cause them to attract one another. Thus, the speed of each cart increases. At a certain instant before the carts collide, the first cart's velocity is +3.5 m/s, and the second cart's velocity is -1.4 m/s. (a) What is the total momentum of the system of the two carts at this instant?...

    Cart A (mass 2.0 kg) and Cart B (mass 3.0 kg) are separated by a compressed spring and attached to each other by a string. Initially they are sitting at rest on a frictionless surface. When the string is burned, Cart A moves to the left at 1.5 m/s. Cart B moves to the right and encounters a rough surface. Cart B comes to a stop after traveling a distance of 0.35 m on the rough surface. What is the...

    A glider with mass m = 0.200 kg sits on a frictionless horizontal air track, connected to a spring with force constant k = 5.20 N/m . You pull on the glider, stretching the spring 0.130 m , and then release it with no initial velocity. The glider begins to move back toward its equilibrium position ( x=0 ). Part A What is the speed of the glider when it returns to x=0 ? Part B What must the initial...
