Truck on Icy Hill 2

As a car moves down an icy hill, a car changes in velocity from \(v = {{ params.v }} \ \rm{km/h}\) to \(v_1 = {{ params.v2 }} \ \rm{km/h}\) over the course of \(t = {{ params.t }} \ \rm{s}\). Was the engine braking or pushing over this interval? What force was put out by the engine? Assume the mass of the car is M and hill slope is \(\theta = {{ params.theta }}^{\circ}\) Assume that braking uphill is negative, accelearting downhill is positive.
