Physics: Unit: Momentum and collisions A truck of mass 1.3 x 104 kg, travelling at 9.0 x 101 km/h, collides with a car of mass 1.1 x 103 kg, travelling at 3.0 x 101 km /h (N). The collision is perfectly inelastic. a) Calculate the magnitude and direction of the velocity of the vehicles immediately after the collision b) Calculate the total kinetic energy before and after the collision described in (a) c) Determine the decrease in kinetic energy during the collision (Hint: = m1Vi1 + m2Vi2 = m1Vf1 + m2Vf2) – you need to use the same formula but need to find the final velocity for second object
