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

Answer:

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
