During a ballistic test a 0.15 kg bullet moving with 60 m/s hits a sandbag and exits from the other side with a velocity of 12 m/s. Sandbag has a thickness of 1.44 m and it applies constant force. a) Using kinematics equations, find the average velocity and the time for the bullet to pass through the sandbag. b) What is the average force exerted by the sandbag?
