Here are the solutions to the problems: Question 2: a) Show that the impulse reduces the speed of the particle but does not reverse its direction. Let the initial velocity be v_i = 4u. The mass of the particle is m_p = 2m. The impulse I = 3mu is directed opposite to the initial motion. If we take the initial direction as positive, the impulse is -3mu. Using the impulse-momentum theorem: I = p = m_p v_f - m_p v_i. -3mu = (2m)v_f - (2m)(4u) -3mu = 2mv_f - 8
