You are standing on top of a 344 m tall building. a drone operated by your friend is headed straight down, at a speed of 37.0 m/s. just as the drone passes you, you release a tennis ball off the roof. how fast is the ball going when it passes the drone?

we need to know the time interval during which the force acts. impulse of force = momentum change

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.
