: Predicting the motion that will occur in a given situation based on the forces applied. Mechanics of Materials
Answer: ( J = Δp = m(v_f - v_i) = 0.2×(-10 - 15) = 0.2×(-25) = -5 , Ns ) (magnitude 5 Ns, direction opposite to initial motion).
A 2 kg block is pushed up a 15° incline by a 50 N force parallel to the incline. The coefficient of friction is 0.25. The block moves 5 m from rest. Find final velocity using work-energy theorem.
