A0.0250-kg bullet is accelerated from rest to a speed of 550 m/s in a 3.00-kg rifle. the pain of the rifles kick is muchworse if you hold the gun loosely a few centimeters from your shoulder rather than holding it tightly against your shoulder.(a) calculate the recoil velocity of the rifle if it is held loosely away from the shoulder. (b) how much kinetic energy does therifle gain? (c) what is the recoil velocity if the rifle is held tightly against the shoulder. making the effective mass 28.0 kg? (d)how much kinetic energy is transferred to the rifleshoulder combination? the pain is related to the amount of kineticenergy, which is significantly less in this latter situation. (e) calculate the momentum of a 110-kg football player running at8.00 m/s. compare the playei’s momentum with the momentum of a hard-thrown 0.410-kg football that has a speed of25.0 m/s. discuss its relationship to this problem.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
