Question

Calculate the average force that must be exerted on 0.145 KG baseball in order to give it an acceleration of 130 m/s²

Answer 1

Given:

mass of ball(m)=0.145kg

acceleration (a)=130 m/s²

Solution:

according to Newton's second law of motion;

$\boxed {F=ma}$

applying this on given condition;

average force that must be exerted on ball is,

$F=(0.145kg)*(130 m/s^2)\\ F=18.9 N$

answer=18.9N
