(a) A rifle fires a bullet and the bullet strikes a tree. The bullet is moving at 1250 m/s when it strikes the tree and the bullet follows a straight-line path, coming to rest 0.44 m deep in the wood of the tree. Assume the acceleration is constant as the bullet slows in the wood. Calculate the acceleration of the slowing bullet in the tree.

(b) Calculate the time for the bullet to move the 0.44 m into the tree.

    A muzzle-loading rifle fires 22LR bullets such that as they travel down the barrel of the rifle their speed is given by v (-4.75 10t2(2.55 x 105)t, where v is in meters per second and t is in seconds. The acceleration of the bullet just as it leaves the barrel is zero. (a) Determine the acceleration (in m/s) and position (in m) of the bullet as a function of time when the bullet is in the barrel. (Use the following...
