A store clerk pulls three loaded shopping carts connected with two horizontal cords to help customers load their carts. Cart 1 has a mass of 9.1 kg, cart 2 has a mass of 12 kg, and cart 3 has a mass of 8.7 kg. Assume friction is negligible. A third cord, which pulls on cart 1 and is at an angle of 23 degrees above the horizontal, has a tension of magnitude 29 N. a) Find the magnitude of the acceleration of the carts.
b) Find the magnitude of the tension in the cord between m3 and m2.
c) Find the magnitude of tension in the cord between m2 and m1

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
