i) ii) Problem 2: A box with a mass of 50 kg is sliding down a frictionless ramp with a velocity of (-10, -7.5) m/sec at time t = 0. Note that the force F₁ acts parallel to the ramp. Gravity is pointing downwards (negative y-direction). Given this information, answer the questions below. F2 = 80 N F₁ = 60 N y 3 4 0 x What is the acceleration of the box? Please report answer as a vector with respect to the Cartesian Coordinate system provided. What is the velocity of the box after 2 seconds have elapsed? Please report answer as a vector with respect to the Cartesian Coordinate system provided.
