The 450-kg mine car is hoisted up the incline using the cable and motor M. For a short time, the force in the cable is F= (3000t2) N, where t is in seconds. (Figure 1) Part A If the car has an initial velocity ₁ = 2m/s at s = 0 and t = 0, determine the distance the plane when t = 3 s Express your answer to three significant figures and include the appropriate units. 8 = Submit μA Value Units My Answers Give Up ? moves up

Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.
