A 1200 kg car moving at 35kph runs into and sticks to a parked 1000kg car. the collision takes 0.15s and after the crash the car's wheels lock and they skid to a stop on the mu= 0.40 road. the final speed of both cars is 5.3m/s a) find the distance

2. ## physics

need help with this question please a 1kg block starts at rest and slides down the incline. the coefficient of friction between the incline and the block is 0.1. The height of the incline is 2m, and the angle is 30 degrees. use energy consideration to find
