One day a responsible young college student is driving his blue car (m = 931 kg) in an easterly direction and obeying the traffic laws with a leisurely velocity of v, = 12.12 m/s. Out of nowhere comes a crazed soccer mom driving her red minivan (M = 1261 kg) in a northerly direction at the insane velocity of V = 21.81 m/s crashing straight into the innocent student. Their vehicles intertwine into a tangled pile of wreckage that eventually slides to a stop. We'll take the coefficient of friction t be: lk = 0.623. d=? V,(wreckage) v,(car) V=? V,(van) Not to scale The following summarizes the sequence of events occur: • 1-2: The cars suffer an inelastic collision. • 2 → 3: The cars slide to a stop. Determine all the following: The x-component of the velocity of the wreckage immediately after the collision: V2x = The y-component of the velocity of the wreckage immediately after the collision: V2y = m/s The magnitude of the velocity of the wreckage immediately after the collision: V2 = m/s The direction at which the wreckage slides: 0 = m/s The distance the wreckage slides before coming to a stop: d = degrees meters NOTE: Use the "mathematician's angle" to specify the direction.
