A 5.00-g bullet moving with an initial speed of vi = 420 m/s isfired into and passes through a 1.00-kg block as shown in thefigure below. The block, initially at rest on a frictionless,horizontal surface, is connected to a spring with force constant910 N/m. The block moves d = 5.60 cm to the right after impactbefore being brought to rest by the spring.
a) Find the speed at which the bullet emerges from the block
(b) Find the amount of initial kinetic energy of the bullet that isconverted into internal energy in bulletâblock system during thecollision.
