Question 5 of 20 A person throws a 0.12-kg ball straight up into the air. It reaches a height of 15 m. What is the force on the ball as it begins to fall? (The acceleration due to gravity is 9.81 m/s2) O A. 4.32 N B. 2.06 N C. 5.45 N D. 1.18 N

d

Explanation:

I got this one wrong, but I wanted to give a helping hand and give y'all the right answer

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.
