A 1,652 kg car moving east at 12 m/s collides with a 1,526 kg car moving south at 15 m/s and the two cars stick together after the collision.
a) Find the velocity of the cars right after the collision?
b) Find how much kinetic energy was converted to another form of energy during the collision?
Two masses of 1.50 kg each, connected by a string, slide down a ramp making an angle of 37° with the horizontal. The coefficient of kinetic friction between M1 and the ramp is 0.39. The coefficient of kinetic friction between M2 and the ramp is 0.14...
