Q4: Car B is initially stationary and is struck by carA moving with initial speed v, = 20 mi/hr. The carsbecome entangled and move together with speed v'after the collision. If the time duration of thecollision is 0.1 sec, determine (a) the common finalspeed v', (b) the average acceleration of each carduring the collision, and (c) the magnitude R of theaverage force exerted by each car on the other carduring the impact. All brakes are released during thecollision.| Ans. (a) v= 13.33 mi/hr, (b)a = 97.8 ft/s',ag =195.6 ft/s , (c) R = 12, 150 lb |4000 lb2000 lb20 mi/hrAB

An ice skater with mass = mi goes skating while carrying a bag of sand with initial mass = m0 . At one point, she gives herself a constant initial velocity v0 , and then slowly pours the sand out of the bag at a constant rate κ. Is she speeding up or slowing down? Write out an expression for the velocity as a function of time. How long does it take for her velocity to change by a factor of 2? Your answer can include mi, m0, v0, and κ.
