A 2.2 kilogram cart is rolling along a frictionless, horizontal track towards a 1.2 kilogram 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 +3.3 m/s, and the second cart's velocity is -1.2 m/s.
(a) Find the total momentum of the system of the two carts at this instant?
(b) Find the velocity of the first cart when the second cart was still at rest?
A 105 kg fullback is running at 4.8 m/s to the east and is stopped in 0.75 s by a head-on tackle by a tackler running due west. Calculate the average force exerted on the tackler
Suppose a 5.0 meter diameter telescope were constructed on the dark side of the moon. The viewing there (except for brief periods of sunlight) would be excellent. As an example, what would be the separation between two objects that could just be r..
