Answer:
<u>75 Newton's</u>
Explanation:
Mass = 15 kg
Acceleration = 
According to Newton's second law, F = ma.
Here, m denotes mass of an object and aa denotes the acceleration, and F denotes the force acting on an object. In other language, force is equal to the mass of an object times its acceleration.
Put m = 15, a = 5m in F = ma
Therefore,
F = 15(5)
= 75 newtons
Answer:
Competition.
