# Part one:

a block is at rest on the incline shown in

the figure. the coefficients of static and kinetic friction are µs = 0.75 and µk = 0.64,

respectively.

the acceleration of gravity is 9.8 m/s^2.

what is the frictional force acting on the

42 kg mass?

answer in units of n.

part two:

what is the largest angle which the incline

can have so that the mass does not slide down

the incline?

answer in units of ◦

part three:

what is the acceleration of the block down

the incline if the angle of the incline is 44 ◦?

answer in units of m/s^2
