A ball has a mass of 140 g. What is the force needed to accelerate the ball at 25 m/s2? (Formula: F=ma)

3.5 Newton

Explanation:

We are given;

Mass of the ball = 140 g

Acceleration = 25 m/s²

Required to find the force;

According to Newton's second law of motion, the resultant force on a body in motion and the rate of change in linear momentum are directly proportional.

That is;

Thus; F = ma, where F is the resultant force, m is the mass and a is the acceleration.

To get the force we substitute the value of m and a in the formula;

Therefore;

F = 0.14 kg * 25 m/s²

= 3.5 N

Hence, the force needed to accelerate the ball is 3.5 N

3.5Newton of force is needed to accelerate 140g of ball at 25m/s2.

We have,

Mass (m) : 140g : 140/1000 kg: 0.14g

(Mass should be in SI unit)

Acceleration (a) : 25m/s2

We khow that,

F=ma

Or, F=0.14*25 kgm/s2

Or, F=3.5Kgm/s2

F=3.5N
