Answer:</h3>
3.5 Newton
<h3>
Explanation:</h3>
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;
![F \alpha \frac{Mv-Mu}{t}](https://tex.z-dn.net/?f=F%20%5Calpha%20%5Cfrac%7BMv-Mu%7D%7Bt%7D)
- 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
