A 1700 kg car moving east at 17 m/s collides with a 1800 kg car
moving south at 20 m/s, and the two cars stick together. Consider
east the positive x-direction and north the positive
y-direction.
a) What is the x-component of the initial momentum before the
collision? ( -7100 kg·m/s, 64900 kg·m/s or 28900 kg·m/s)
b) What is the y-component of the initial momentum before the
collision? (-36000 kg·m/s, -7100 kg·m/s, 64900 kg·m/s or 36000
kg·m/s)
c) What is...
