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 tranvelled before skidding to a stop (3.6m)
b) the impact force on both cars (35000N)
c) the energy absorbed (26kJ)
Are the numbers in parentheses known correct answers or you own calculated results?
