In the figure provided, a 255 kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the mass on the left is m=100. kg, what is the magnitude of the acceleration of the 255 kg crate? Assume the rope and pulley are massless.

Answer 1

No diagram, assuming to the right is fall straight down, one on the left is horizontal, no friction.

F=ma
255*g=(255+100) a
solve for a
