<h3>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;
- 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

Explanation:
A single displacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.
Synthesis reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
Combustion is a type of chemical reaction in which hydrocarbons burn in the presence of oxygen to form carbon dioxide and water along with heat.
