The figure below shows a bullet of mass 80 g traveling horizontally towards the east with speed 450 m/s,which strikes a block of mass 2.5 kg that is initially at rest on a frictionless table.After striking the block, the bullet is embedded in the block and the block and the bullet move together asone unit.a. What is the speed of the block/bullet combination immediately after the impact? HintsThe speed of the combination ism/s.b. What is the magnitude and direction of the impulse by the block on the bullet? HintsThe block exerts an impulse ofNċs on the bullet Select an answerc. What is the magnitude and direction of the impulse from the bullet on the block?The bullet exerts an impulse ofd. If it took 3 ms for the bullet to change the speed from 450 m/s to the final speed after impact, what isthe average force between the block and the bullet during this time?HintsNċs on the block Select an answer .The magnitude of the average force isN.e. Of the kinetic energy initially present in the bullet, what percentage still remains as kinetic energy ofthe block/bullet? HintsOf the original kinetic energy,% remains as kinetic energy of the block/bullet.

You drop a steel ball and a clay ball, both of the same mass, from the same distance. The steel ball strikes the ground and rebounds with almost the same speed. The clay ball strikes the ground and sticks. Assume the collisions occur over roughly the same amount of time. Which ball exerted a greater force on the ground? Select the correct answer with the best explanation. A. The two exert the same force. Since they collide with the same initial momentum, they will exert thesame force.B. The clay ball exerts the greater force. Since it starts with some momentum and ends with no momen- tum, it undergoes a greater change in momentum than the steel ball, which rebounds with the same momentum (no change).C. The clay ball exerts the greater force. All of its energy is transferred to the floor, whereas the steelball rebounds with the same kinetic energy, doing no work on the floor.D. The steel ball exerts the greater force. Since it starts with some momentum and it reverses the direction of…
