Inclined Ramp_4

Some guy is pulling a box up a ramp. The ramp is inclined at 20° to the horizontal floor. The rope pulling up the box is at an angle of 30° to the ramp. If the mass of the box is 50 kg, and the tension in the rope is 240 N, (a) then estimate the magnitude of the acceleration |𝑎_𝑥 | of the box, (b) determine the magnitude of the contact force |𝐹_𝑁 | exerted by the ramp onto the box . Ignore frictional forces.
