When a man in a cage whose weight is 1000N pulls a rope that is attached on a cage around a fixed pulley,the force he exerts on the floor of the cage is 450N ,if the cage weigh 250N ,find the acceleration

The weight of cage + man is 1250 N and their combined mass is

Mtotal = Wtotal/g = 127.6 kg.

The man and cage accelerate at the same rate, a. Let F be the rope tension force. Consider all forces on the man, including weight and the upward floor force. The man's mass is 102 kg

F - Wman + 450 = F - 550 = 102*a

Now consider all exernal forces on man and cage together:

F -1250 = 127.6 a

Combining the two results in

700 = -25.6 a

a = -0.0366 m/s^2
