Question

To test how good the bumpers of a car weighing 1500 kg are it is made to collide with a wall as shown in figure given . The initial and final velocities of the car are -15.0 m/s and 2.6m/s respectively if the collision lasts for 0.15 s , then find (a) the impulse of the force , (b) the average force exerted on the car​

Answer 1

Answer:

Did you mean: To test how good the bumper of a car weighing 1500 kg are it is made to collide with a wall as shown in figure given . The initial and final velocities of the car are -15.0 m/s and 2.6m/s respectively if the collision lasts for 0.15 s , then find (a) the impulse of the force , (b) the average force exerted on the car

Answer 2

impulse = 26400 kgm/s

average force = 17600 N
