I need help with this asap. I'm on my last attempt and need to get correct. Can you please show all the answers neatly so I can see them. Thank you. 12a

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. N2 Since the floor is rough, it exerts both a normal force , and a frictional force , on the ladder, However, since the wall is frictionless, it exerts only a normal force N2 on the ladder. The ladder has a length of L = 4.50 m, a weight of W - 55.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m = 90 kg is standing on the ladder, determine the following. (a) the forces exerted on the ladder when the person is halfway up the ladder (Enter the magnitude only.) N= IN N2 = (b) the forces exerted on the ladder when the person is three fourths of the way up the ladder (Enter the magnitude only.) M = N2 IN IN
