Question

60 km/h collides with a stationary bus.13600 kg.A car travelling at some velocity veThe car has a mass mɛ =2240 kg, and the bus has a mass mt What is

the momentum of the car before the collision? What is the kinetic energy of the car before the collison? After the collision, the car and truck stick together. What is their speed immediately after the collision? 4.How much energy was lost to deformation of the car and minibus? Suppose instead, that the velocity of car is initially unknown,but the skid marks were found to be 1.74 m long. How fast was the car going before it hit the minibus? Assume a coefficient of kinetic friction for tyres µ = 0.72 and give the speed in km/h.
