Academics

Problem: A machine in an ice factory is capable of exerting 2.78 × 10² N of force to pull large blocks of ice up a slope. The blocks each weigh 1.52 × 10⁴ N.

Part A: Assuming there is no friction, what is the maximum angle that the slope can make with the horizontal if the machine is to be able to complete the task?

I need help to find the maximum angle that the slope can make with the horizontal if the machine is to be able to complete the task.
