A 60 kg crate is lowered using arope over a fixed support. The rope exerts a constant upward forceof 500 N.? Will the crate accelerate? What are the magnitude and direction of the acceleration of thecrate? How long will it take the crate to reach the floor if the height ofthe loading dock is 1.4 m above the floor? How fast is the crate traveling when it hits the floor?
