Question

A ball going 20 m/s bounces off a wall at a velocity of -12 m/s and goes the opposite direction. If this is a 2 kg and the time it touches the wall is .6 seconds, what is the average force on the wall?

200 m/s at

Expert Solution

Step 1

Answer: Given data,

Initial velocity of ball (u)=20m/s

Final velocity after bounce back (v)=-12 m/s

Negative sign represent that the final velocity is in the opposite direction of initial velocity.

So, we take final velocity is (v)=12m/s

Mass of ball (m)=2kg

Time of contact with the wall (t)=0.6 s

And we know momentum=mass×velocity
