Question

please help. A block with a mass of m is sliding to the right with a velocity of v on a horizontal, frictionless surface. It has a head-on collision with a larger block with a mass of 9m that is initially at rest. After the collision, the blocks are stuck together and move to the right, along the same path, with a velocity of 0.1v. look at the pictures for the options

Answer 1

All external forces excerted on the two block system sum to zero.

All forces exerted on both blocks sum to zero

Step-by-step explanation:

The rate of change of momentum of a body is directly proportional to the resultant external applied force and takes place in the direction in which the force acts i.e. F=ma
