A 0.30 kg toy car with an initial velocity of 4 m/s collides with a 0.5 kg car with an initial velocity of 4 m/s in the opposite direction. If the cars stick together during the collision, what is the final velocity of the two cars? Assume negligible friction. If the collision took 0.005 seconds, what was the force applied by the cars on one another?​

the answer would be 32*f

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.
