A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure.

𝑑=3.75𝑚 above the floor. If a person with a mass of 𝑚=90𝑘𝑔 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.)

𝑁1=𝑁

trinnmmotmoto determine the angle between the ladder and the floor. 𝑁

(b) the forces exerted on the ladder when the person is three-fourths of the way up the ladder (Enter the magnitude only.)
