change in velocity is 3m/s,the force exterted by bat on ball is 4.8N and the acceleration is 30m/s².
<h3>Give some difference between velocity and speed.</h3>
1) Speed is scalar quantity but velocity is vector quantity.
2) Speed is distance followed by an individual with respect to time and velocity is displacement with respect to time .
1) final velocity- intial velocity
25-22= 3m/s
2) The force is
F= ma
. 0.16×30= 4.8N

The force of friction needed to overcome to move the box is 29.4N
According to Newton's second law;
Taking the sum of force along the plane;
This shows that the moving force is equal to the frictional force
Given that
Get the frictional force;
Since
Hence the force of friction needed to overcome to move the box is 29.4N
