A neutron, one of the constituents of a nucleus, is found to pass two points 60 metres apart in a time interval of 1.8 xx 10^(-4) sec . The mass of the neutron is 1.67 xx 10^(-27) kg . Assuming that the speed is constant, its kinetic energy is

A bullet of mass 20g is found is found to pass two points 30cm apart in a time interval of 4s. Calculate the kinetic energy of the bullet if it moves with constant speed.

A bullet of mass 20g is found to pass two points 30m apart in 4 s? Assuming the speed to be constant, find its kinetic energy?
