Question
(a) After traveling 145 m along a straight path, a car reaches a speed of 29 m/ s.
Determine the particle's constant acceleration and the time of travel if it starts
from rest.
(b) The 30-g bullet is fired horizontally into the 400-g block which rests on a smooth
surface. After the bullet becomes embedded into the block, the block moves to
the right 0.39 m before momentarily coming to rest. Determine the speed (v), of
the bullet. The spring has a stiffness k = 200 N/ m and is originally unstretched.
