The principle of conservation of linear momentum states that if in any assigned direction the net external force on a system is zero, then the linear momentum of the system will remain constant in that direction. Answer the following question. Suppose the mass of the cart along with your mass is 100 kg and there are 4 balls each of mass 2 kg in the cart that is now moving at a constant speed 20 ms to the left on the frictionless track. If you throw a ball straight up with a velocity 20 ms, how will the speed of the cart change? |
