A 1120 kg four door sedan hits a 1420 kg minivan that is at rest. The two cars lock together and skid 12.0 m on a level surface before stopping. Police determine that the coefficient of kinetic friction between the tires and the road is 0.70.

a. what is the frictional force acting on the two cars.

b. what was the acceleration of the cars after the collision as they slide across the pavement.

c. what was the speed immediately after the collison ? (before the cars start to slide)

d. was the sedan exceeding the speeding limint of 45 mph before the collision.

e. what was the loss in kinetic energy during the collision.
