for 8 all i did was find the force of gravity which is 9.8 times the mass of the bucket. Then i used the formula N-Fg=ma and since it said to put it in N i found out what N was equal to which was N= Fg+ma. You times the mass of the bucket by the upwards accelleration since its asking what is the force exerted by the rope on the bucket and the force is going upwards. You already know what Fg is (from before) so u have to add Fg by ma and that should be your answer

he's right, just follow that exactly (which is what I said) and you'll get it right
