A big crane pulls a heavy crate upwards from the hull of a containership in the harbour. The weight of the crate is 35 000N. The crane pulls the crate with an upward force of 42 000N. There is some friction involved, due to all the pulleys and wires, of 550N, while the crate is pulled upwards. Calculate the magnitude and direction of the resultant force acting on the crate.

Answer:
6450N ( acting jpwarfs)
Explanation:
force due to crate = 35000N ( downward)
friction due to wire= 550N ( downward)
Total of all forces ( downward) = 35550 N
Crane pulling force = 42000N ( upward)
Total of all forces ( upward) = 42000 N
Sum of all forces = 42000+(-35550) = 6450N
This force is acting upward
