Explanation From the given condition the free body diagram is given below. The sled is being pulled with a constant speed, then the net force on the sled is zero. This is an equilibrium condition then the equations to find angle are, Σ F x = F T cos θ − F k = m a = 0 F T cos θ − F k = 0 (I) Here, F x is the force, F T is the tension force, m is the mass, a is the acceleration, θ is the angle and F k is the friction force. Σ F y = F T sin θ + F N − F g = m a = 0 F T sin θ + F N − F g = 0 (II) Here, F g is the gravitational force and F N is the normal force. Write the equation for gravitational force. F g = m g (III) Here, g is the acceleration due to gravity. Write the equation for friction force. F k = μ k F N (IV) Here, μ k is the coefficient of friction
