The mass of the hunter (including his gun) is 72.5 kg, and the hunter holds tight to the gun after firing it. Find the recoil velocity of the hunter if he fires the rifle (a) horizontally and (b) at 56.0° above the horizontal.

A cannon is mounted on a railway flatcar, the muzzle elevated to 33.2° and pointed in the direction of the track. The cannon fires a 0.80-metric-ton projectile at 0.90 km/s.
(a) If the flatcar and cannon together have a mass of 36.0 metric tons (not including the projectile), what is the initial recoil speed of the flatcar?
m/s
(b) In this problem, it appears that momentum in the y-direction is not conserved. Explain what happens to it.
A mark man holds a rifle of mass 3.00kg loosely ,so it can recoil freely.he fires a bullet of mass 5.00g horizontally with a velocity relative to the ground of 300m/s.what is the recoil velocity of the rifle ?

- A rocket has total mass Mi = 360 kg, including Mfuel = 330 kg of fuel and oxidizer. In interstellar space, it starts from rest at the position x = 0, turns on its engine at time t = 0, and puts out exhaust with relative speed ve = 1 500 m/s at the constant rate k = 2.50 kg/s. The fuel will last for a burn time of Tb = Mfuel/k = 330 kg/(2.5 kg/s) = 132 s.
