Answer:
147 newton.
Explanation:
Force is the product of mass and acceleration. The formula of force is given below: Force = mass x acceleration, but due to height we put gravity instead of acceleration. So by putting values of mass i. e. 15 kg and gravity i. e. 9.8 meter/ second in the formula we get the net force of the ball which is 147 newton or 147 kg meter/second square.
