A 0.43 kg football is thrown with a velocity

of 12 m/s to the right. A stationary receiver

catches the ball and brings it to rest in 0.023

s.

What is the force exerted on the receiver?

Answer in units of N

Answer in units of N

Expert's answer

F=m*a, second newton's law.

F=0.43*a -& exerted force

a=v/t=12*0.023 - we find the acceleration, that stopped the ball while force was exerted

So F=0.43*12/0.023=224 N - we put in numbers to find the answer

F=0.43*a -& exerted force

a=v/t=12*0.023 - we find the acceleration, that stopped the ball while force was exerted

So F=0.43*12/0.023=224 N - we put in numbers to find the answer
