Question:

The M79 grenade launcher was first used by the U.S. Army in 1961. It fires a grenade with an approximate mass m ≈ 7.0 kg at a speed of 75 m/s.

(a) If a soldier fires the M79 horizontally while standing on a very slippery surface, what is the recoil speed of the soldier? Take the mass of the soldier plus M79 to be 100 kg.

(b) The barrel of the M79 is 36 cm long. Estimate the average recoil force on the soldier.
