A 0.0260 kg bullet is accelerated from rest to a speed of 545 m/s in a 2.90 kg rife. The pain of the n's than holding it tightly against your shoulder (Assume the bullet meves in the direction) worse if you hold the gun loosely a few centimeters from your shoulder rather (a) Calculate the recoll velocity (in m/s) of the rifle if it is held loosely away from the shoulder (Indicate the direction w sign of your answer m/x (b) How much kinetic energy (in 3) does the riffe gain) (c) What is the recoll velocity (in m/s) if the oulder, making the effective mass 28.0 kg? (Indicate the direction with the sign of your a m/s (4) How much kinetic energy (in 3) is transferred to shoulder combination? The pain is related to the amount of kinetic energy, which is significantly less in this letter situation (e) Calculate the momentum of a 110 kg football player running at 8.00 m/s. Compare the player's momentum with the momentum of a hard-thrown 0.410 kg football that has a speed of 25.0 m/s. Player Powt Discuss its relationship to this problem
