AT&T; 14:13 40%) learningcatalytics.co Session 32226111 Log out 1 2 3 45 multiple choice question In each of the six figures below, a cart that has a motor and brakes is traveling either up or down an incline at constant speed. The carts are identical, but they carry either a 2 kg or 4 kg load, and are on one of two inclines. Incline angles, cart masses and speeds are given in each figure. 25 Choose the option that correctly ranks the carts in order of the magnitude of the net force acting each cart from largest to smallest. That is put the cart with the largest force first, and the cart with the smallest force last. A.

Explanation / Answer

All the carts are moving with constant velocity. So there is no acceleration on any cart, hence net force on all the carts is zero.
