Two balls of mass 0.5 kg and 0.8 kg are connected by a low-massspring. This device is thrown through the air with low speed, soair resistance is negligible. The motion is complicated: the ballswhirl around each other, and at the same time the system vibrates,with continually changing stretch of the spring. At a particularinstant, the 0.5 kg ball has a velocity ‹ 6, -5, 3 › m/s and the0.8 kg ball has a velocity ‹ 4, 3, 7 › m/s.

(a) At this instant, what is the total momentum of thedevice?
total = kg · m/s

(b) What is the net gravitational (vector) force exerted by theEarth on the device?
grav = N

(c) At a time 0.09 seconds later, what is the total momentum of thedevice?
total = kg · m/s

A 2.3 kg cart is rolling across a frictionless, horizontal track toward a 1.5 kg cart that is held initially at rest. The cars are loaded with strong magnets that cause them to attract one another. Thus, the speed of each car increases. At a certain instant before the cars collide, the first car's velocity is 4.5 m/s and the second car's velocity is -1.9 m/s. (A) what is the total momentum of the system of the two cars at this instant? (B) What was the velocity of the first cart when the second cart was still at rest?
