Answer:
The force exerted by the floor is 80 N.
Explanation:
Given that,
Mass of ball = 0.5 kg
Velocity= 4 m/s
Time t = 0.05 s
When the ball rebounds then the kinetic energy is
Where, m = mass of ball
v = velocity of ball
Put the value into the formula
The average force exerted by the floor on the ball = change in kinetic energy over collision time
Hence, The force exerted by the floor is 80 N.
