Pls help me answer this 4 questions its about energy transfer in physics thanks 1.A 73.8 kg diver jumps from a 11.8 m platform into the pool below. Determine her PEg at the top of the platform. 2.A bullet with a mass of 0.018 kg is fired from a rifle with a barrel that is 0.83 m long. Assuming that the force exerted by the expanding gas to be a constant 8,777 N, what speed would the bullet reach? 3.A spring does 5.0 J of work on a 0.10 kg ball in a pinball machine. The ball's resulting speed just after leaving the spring is...? 4.A baseball (m= 0.142 kg) travelling at 25.1 m/s moves a fielder's glove backward 0.31 m when the ball is caught. Neglect any change in height and assume all the energy transfers from the ball to the glove. How much work was done on the glove
