A soccer ball of mass 0.4 kg, initially at rest, acquires a speed of 5 m/s immediately
after being kicked by a force of 20 N. How long did this force act on the ball?



Sagot :

The force will exert its force on the soccer ball for 0.1 seconds.

What is force?

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Force is defined as the product of mass and acceleration. Its unit is Newton.

Given data;

Force,F = 20 N

Mass,m = 0.4 kg

Initial velocity,u = m/sec

Final velocity,v =0

Time,t = ? sec

From Newton's second law, the force is found as;

F=[m(v-u)]/t

20=[0.4(5-0)]/t

t = 0.1 sec

Hence the time for which the force act on the soccer ball will be 0.1 sec.
