In the photo, the man has a mass of 60 kg and the crate has a mass of 100 kg. The coefficient of static friction between his shoes and the ground is μs = 0.4 and between the crate and the ground is μc = 0.3.

a) Determine if the man is able to move the crate using the rope-and-pulley system shown.

b) Prove your answer to part A by calculating the static frictional force F between the man's shoes and the ground required to move the crate and the maximum static frictional force Fmax which can be developed.

Express your answers in newtons to three significant figures separated by a comma.
