Round all answers to 4 significant figures. (Mote: Don't forget to use proper SigFig's etc for 1 full mark.) [8 marks] a) Determine the mass defect of the nucleus of plutonium-239. Note: Make sure to first use the AMU mass instead of the mass in kg to find the atomic mass of plutonium. Give your final answer in kg by converting only at the end. (4) b) Determine the binding energy of the nucleus of plutonium-239. Give your answer in MeV. (Remember not to use the shortened path using 930 in your solution as it will give you the wrong answer.)

She is curious as to how far she could throw a rock before it hits the water. Recognizing that it would be unsafe to actually throw the rock, she decides to work out the answer mathematically. She knows that she can throw the ball horizontally at a speed of 35.0 m/s. How far {horizontally) will the ball be when it hits the ground? Make sure to draw a diagram.
