A car of mass 2400 kg collides with a truck of mass 4500 kg at the intersection of horizontal roads. The vehicles stick together and slide immediately after the collision. The x- and y-components of the car’s velocity just before the collision are (36, 0) m/s, respectively, and the same components of the truck’s velocity just before the collision are (-15, 25) m/s.

a. calculate the x component of the velocity of the combined car and truck immediately after the collision, in meters per second.

b. calculate the y component of the velocity of the combined car and truck immediately after the collision, in meters per second.

c. this collision is highly inelastic. calculate the loss of total kinetic energy during the collisin in joules

d. find the increase of internal energy of the car and the truck (due to heating and deformation) in joules
