Homework Statement
a 500 lb gun fires a 2lb projectile with a muzzle velocity of 1600 ft/s. if the recoil is against a constant resisting force of 400 lb, find the time taken to bring the gun to rest and the distance it recoils.
a) .20s, .80ft b) .25 s, .80 ft c) .25 s, .85 ft d) .15 s, .75 ft
Homework Equations
p=mv
The Attempt at a Solution
initial recoil is -6.4 ft/s (500*-6.4=2*1600)
i'm not sure where to start on this...the constant resisting force means what? I've never come across that before.
