Question

please help

A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to move off at an angle theta'2=45 degree. The neutron's initial speed is 3.1 times 105m/s. Determine the angle of the neutron, theta'1, after the collision. Express your answer using two significant figures. Determine the speeds of the two particles, 'n and 'He, after the collision. Express your answers using two significant figures. Enter your answers numerically separated by a comma.
