At a shooting competition, a contestant fires and a 13.0 bullet leaves the rifle with a muzzle speed of 130 . The bullet hits the thick target backing and stops after traveling 4.10 .
-
bullet = 13gm
muzzle speed = 130 m/s
travel depth = 4.1 cm
I hope that's what you meant. Discipline yourself to use units.
Under the above assumptions,
1/2 mv^2 = F*s
F = 1/2 mv^2 / s = (1/2 * 0.013 kg * 130^2) / 0.041m = 2679N
muzzle speed = 130 m/s
travel depth = 4.1 cm
