Liz and Jacqueline each hit a golf ball off the top of an ocean cliff. Liz's ball
has a horizontal velocity of 20 m/s and a vertical velocity of 1 m/s.
Jacqueline's ball has a horizontal velocity of 20 m/s and a vertical velocity of
2 m/s. Which of the following statements is true?
A. The two balls will stay in the air the same time, but Jacqueline's
will travel farther.
B. The two balls will stay in the air the same time, but Liz's will travel
farther.

C. Jacqueline's ball will stay in the air longer and travel farther.
W

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.
