Problem 1: A box, with a mass of 50 kg, is sliding down a frictionless ramp as depicted in Figure 1. Note that the force F₁ acts parallel to the ramp. Gravity is pointing downwards (negative y-direction). What is the acceleration of the box? Solve this problem using Normal and Tangential Coordinates and report your answer as a vector in Normal and Tangential Coordinates. y X F2 = 80 N F₁ = 60 N 2 Figure 1: Box sliding down ramp. 5
