a 1 kg ball of clay is thrown horizontally at a 1 kg block of woods which is at rest on the floor after which they get stuck together . (a) if the initial velocity of the clay is 1 m/s. what is the velocity after collisions ? B. what is the total kinetic energy of the system before collision? c. what is the total kinetic energy of the system after collision. what is the total loss of kinetic energy of the system ? e how much kinetic energy did the ball of clay lose because of the impact?
