Problem 11: A man is attempting to lift a crate using a two part pulley system as shown in the image. The crate has mass \( m_{2}=68 \mathrm{~kg} \), and the man has \( m_{l}=75 \mathrm{~kg} \). He pulls downward on the rope with a force of magnitude \( F=564 \mathrm{~N} \). The pulleys are massless and frictionless. Find the acceleration of the block?
