John swing the bat (mass of .5 kg) at 20 m/s (velocity) It hits the ground for .1 seconds (time), what force did the baseball bat exert on the ground.

Mar 19th, 2015

Force = m ( v - u ) / t

V = 0

U = 20 m/s

m = 0.5 kg

t = 0.1 sec.

Force = 0.5 ( 0 - 20 ) / 0.1 kg m s^-2

Force = -100 Newton

Answer = -100 Newton
