Question

A 12,000 kg truck moving to the right at 22 m/s collides with and sticks to a 1200 kg car moving to the right at 16 m/s. What speed do the two vehicles move after the collision in what direction

Calculate the Kinetic energy converted to heat sound and instructive work in the collision described

Answer 1

M1*V1 + M2*V2 = M1*V + M2*V.

M1 = 12,000 kg, V1 = 22 m/s.
M2 = 1200 kg, V2 = 16 m/s.
V = ?.
