A box (2 kg) moves with a speed of 0.6 ms"' along

A box (2 kg) moves with a speed of 0.6 ms"' along a straight frictionless horizontal path and collides with a stationary box (2 kg). The collision is perfectly inelastic. Assume no air drag. (a) Calculate the speed of the two boxes immediately after the collision. After the collision, the two boxes travel in a straight horizontal path, which has friction. (b) The two boxes come to rest after traveling 0.5 m. Calculate the magnitude of the force of kinetic friction. QUESTION 2 Consider a system of two particles moving horizontally in opposite directions away from cach other atong the x-axis. There is no friction of any kind. Initially, Particle 1 (0.3kg) moves to the left at 5 ms and Particle 2 (0.5 kg) moves to the right at 3 ms". (a) What is the initial velocity of the center of mass of the system? (b) A force of 2 N is then applied to the system for 2 seconds. What is the final velocity of the centre of mass?
