A 5.00-g bullet moving with an initial speed of v₁ = 390 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 860 N/m. The block moves d = 5.40 cm to the right after impact before being brought to rest by the spring. Vi (a) Find the speed at which the bullet emerges from the block. m/s (b) Find the amount of initial kinetic energy of the bullet that is converted into internal energy in bullet-block system during the collision.
