Question: A certain mass, m = 2 kg, moves on a surface inclined at an angle = 30 above the horizontal. Its initial velocity is

A certain mass, m = 2 kg, moves on a surface inclined at an angle ϕ = 30° above the horizontal. Its initial velocity is (0) = 3 m/s up the incline. An external force of f₁ = 5 N acts on it parallel to and up the incline. The coefficient of Coulomb friction is µ = 0.2. Use the Sign block and create a Simulink model to solve for the velocity of the mass until the mass comes to rest. Use the model to determine the time at which the mass comes to rest.
