Answer #1

Mass of Garbage truck,M=1.4104 kg

speed of truck,v=30 m/s

Momentum of truck,P=Mv=1.410430=4.2105 kg-m/s

mass of trash,m=6kg

speed of trash=P/m=(4.2105)/6=7.0104 m/s

    Let’s begin by calculating the total momentum of two moving objects. Suppose a small compact car with a mass of 1000 kg is traveling north on Morewood Avenue at a speed of 15 m/sm/s. At the intersection of Morewood and Fifth Avenues, it collides with a truck with a mass of 2000 kg that is traveling east on Fifth Avenue at 10 m/sm/s. Treating each vehicle as a particle, find the total momentum (magnitude and direction) just before the collision....
