A ball of mass 4.0 kg moving with an initial velocity of 2.0 meters per second to the right collides elastically with another ball of mass 6.0 kg moving within velocity of 4.0 meters per second to the left after the Collision the first ball is moving with a velocity of 5.2 m/s to the left. What is the velocity of the second ball after the collision?

the force on the thing and the distance the force moves the thing

vapour or gas assuming atmospheriv pressure

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
