a 700 kg car is waiting at a stop light, when a 1200 kg car coasting at 4.0m/s strikes it from the rear. the cars do not stick together, nor is the collision perfectly elastic. The front car moves ahead at 5m/s after the collision. What is the speed of the rear car after the collision?

A 1200-kg car is moving at 16.0 m/s due north. A 1500-kg car is moving at 20.0 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. 1) Determine the speed of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.) m/sm/s 2) Determine the direction of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.)

In
the "before" part of the figure, car A (mass 1200 kg) is stopped at
a traffic light when it is rear-ended by car B (mass 1200 kg). Both
cars then slide with locked wheels until the frictional force from
the slick road (with a low μk of 0.16) stops them, at distances dA
= 8.0 m and dB = 5.3 m. What are the speeds of (a) car A and (b)
car B at the start of the sliding,...
