Suppose that two workers simultaneously push on a heavy 325 kg crate with forces F. (magnitude 750. N) and R (magnitude 500. N), at directions as shown in the diagram. Assume that both of these forces remain constant as the crate moves. The floor is exactly horizontal (level). ou may wish to solve parts (b) simulaneously: (a) a. (5 pts.) If the crate starts out with zero friction between with crate and the floor, find the magnitude and direction of the resulting acceleration of the crate. Show your work. b. (2 pts. Find the magnitude of the normal force from the floor. Show your work. c. (3 pts.) If the crate starts from rest, and the workers’ forces remain constant at all times, how much time does it take for the crate to travel 6.00 meters from its starting position?
