I need help answering parts A, B, C,and D

(10 0/0} Problem 3: One of the waste products of a nuclear reactor is plutonium239 (EsgPu). This nucleus is radioactive and decays by splitting into a helium'4 nucleus and a uranium235 nucleus (4He + ESSUL the latter of which is also radioactive and 1will itself deca}r some time later. The energy emitted in the plutonium decay is 8.40 X 10'13 I and is entirelyr converted into the kinetic energy of the helium and uranium nuclei. The mass of the helium nucleus is 6.68 K 10'27 kg 7 while that ofthe uranium is 3.92 X 10'25 kg {note that the ratio ofthe masses is 4 to 235}. is. 25% Part (3} Calculate the speed ofthe l-le= in meters per second= assuming the plutonium nucleus is originally at rest.
