Can you help me to do questions 3 and 4 only. Must draw an energy bar chart and show all work

I'ulIlU. F'vvr- I For each problem, draw energy bar charts and show all work on a clean piece of paper. 1. l.- A ripe, 0.6kg apple falls off a tree branch that is 3m above the ground. a. How fast is the apple moving just before it hits the ground? b. How fast is the apple moving when it is halfway to the ground? 0. At what hbight is it moving with half of its speed that it has right before it hits the ground? A boy reaches out of a 10m high window in an apartment building and throws a 0.25kg ball upwards with a speed of 15m/s. a. How high does the ball go above the ground? b. How fast is the ball moving when it reaches the ground below? A pole vaulter with a mass of 74 kg wants to clear a bar that is 5.6m above the ground. The pole vaulter's center of mass is already 1.2m above the ground The pole converts 100% of the kinetic energy the vaulter has when running into gravitational potential energy to lift her over the bar. a. How fast must the vaulter run in order to clear the bar? b. How fast must the vaulter run if only 80% of her kinetic energy is converted into gravitational potential energy instead of 100% The cart on the table has a mass of 3kg and can roll without friction along the tabletop. The hanging block has a mass of 1kg and is attached by a string to the cart (over the pulley). The hanging block is released at a height of 0.8m and the cart and block start to move. How fast is the cart moving when the hanging block reaches the oor? A I_I__I. :- L-_L_:_~ -L n.\" $5.. 1\" Main kill
