A 500 g block, sliding on horizontal surface, collides head-on, and sticks to, a 200 g block at rest. A) Find the speed of the combination after the collision if the 500 g block was was moving at 5.00 m/s before the collision. B) If the coefficient of kinetic friction between the blocks and the floor is 0.315, how much further with the blocks go before stopping?

Answer #1

using momentum conservation find their final speed after collision.

Also we have given kinetic friction coefficient and find deacceleration or decreasing acceleration due to friction and using equation of motion solve for distance before coming at rest.
