the kinetic energy is 8100 j.
mass is 50.0kg and velocity is 18 m/s, the kinetic energy is:
as we know the formula of kinetic energy which is k.e = ½ ( mv ^ 2 ),
mass = m = 50.0kg
velocity = v = 18 m / s,
by putting values in the formula,
k.e = ½ ( mv ^ 2 ),
k.e = ½ ( 50kg ) . ( 18 m / s ) ^ 2
k.e = ½ ( 50kg ) . ( 324 ),
=> k.e = 1/2 ( 16200 ),
=> k.e = 16200 / 2,
=> k.e = 8100j.
hence, the kinetic energy ( k.e ) is 8100 joule ( j ).
