A bullet of mass 10 g is fired horizontally into a 4 kg wooden block resting on a horizontal surface. The coefficient of kinetic friction between the block and the surface is 0.25 . The bullet is embadded the block and the combination moves a distance of 20 m before coming to rest. Find the speed of the bullet just before striking the block. (g=10m//s^(2))

A bullet of mass 10 gram is fired horizontally into a 5 kg wooden block at rest on a horizontal surface The coefficient of kinetic friction between the block and the surface is 0.1 Calculate the speed of the bullet striking the block if the combination moves 20 m before coming rest .

A block of mass 4 kg is resting on a horizontal table and a force of 10 N is applied on it in the horizontal direction. The coefficient of kinetic friction between the block and the table is 0.1. The work done in sqrt(20) s

A bullet of mass 5gm is fired horizontally into block of mass 1kg at rest on a horizontal surface and gets embedded in it. The combination moves 5m before coming to rest. If mu_(k)=0.40 , what is the speed with which the bullet strikes the block ?

A 441 gm bullet strikes an d becomes embedded in a 1.54 kg block of wood placed on a horizonatal surface just in front of the gun. If the coefcient of kinetic friction between the block and the surface is 0.28, and the impact drives the block a distance of 18 m before it comes to rest, what was the muzzle speed of the bullet ?

A wooden block of mass M resting on a rough horizontal surface is pulled with a force T at an angle q to the horizontal. If m is coefficient of kinetic friction between the block and the surface, the acceleration of the block is
