Reference no: EM13543679

A rifle with a weight of 20 N fires a 3.5-g bullet with a speed of 250 m/s. (a) Find the recoil speed of the rifle. Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 10%. Double check your calculations. m/s (b) If a 800-N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle. m/s
