In a particular crash test, a car of mass 1500 kg collies with a wall as shown in fig. The initial and final velocities on the car are →vi=-15.0ˆims-1 and →vf=5.00ˆims-1, respectively. If the collision lasts 0.150s, find the impulse caused by the collision and the average force exerted on the car.

Impulse and Impulsive Force || Collision

Two identical blocks A and B connected by massless string, are placed on a frictionless horizontal plane. A bullet havig the same mass, moving with speed u strickes block B from behind as shown. If the bullet gets embedded into block B then find a. the velocity of A,B,C after collision. b. impulse on A due to tension in the string, c. impulse on C due to normal force of collision, d. impulse on B due to normal force of collision.
