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.

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp, max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
