please do all ! thank you

INSTRUCTIONS: Answer the subsequent set of questions to solve the "Goal of this problem. We recommend you write out your answer to compare to the particular questions as you go along, as if you were going to submit it fully SETUP: As shown in the figure, a painter climbs along a uniform ladder leaned up against a smooth wall. There is static friction between the feet of the ladder and the ground. The painter is a distance al from the base of the ladder, as measured along the ladder (and z is given as a value between 0 < < 1). We will use the following parameters, with their associated variables: • m-mass of the painter (and their equipment) • Mladdermass of the ladder • L = length of the ladder • a numerical value greater than O but less or equal to 1 • N-normal from from the floor to the ladder • Fforce acting from the wall to the ladder • H, - coefficient of static friction between the ladder and the floor • e-angle between the ladder and the horizontal FIGURE:
