A 5.00-g bullet moving with an initial speed of vi = 430 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 850 N/m. a. If the block moves a distance d= 5.40 cm to the right after impact before being brought to rest by the spring, what was the kinetic energy of the block after the bullet passed through the block? b. Hence find the final velocity v of the bullet. [Remember to use S.I. units] -

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
