y Col- Of v/4 after the collision. (a) What tme Fatio of the final kinetic energy of the system to the initial kinetic energy? (b) What is the ratio of the mass of the more mas- sive object to the mass of the less massive object? SECTION 9-6 ELASTIC COLLISIONS 35. In the apple-orange collision in Example 9-16, suppose the final velocity of the orange is 1.03 m/s in the negative y direction. What are the final speed and direction of the apple in this case? 36. A 732-kg car stopped at an intersection is rear-ended by a 1720-kg truck moving with a speed of 15.5 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elas- tic, find the final speed of both vehicles after the collision. 37. The collision between be approximately elastic. Calculate the kinetic energy acquired by a hammer and a nail can be considered to a 7.2-g nail when it is struck by a 450-g hammer moving with an initial speed of 8.8 m/s. 38. *. Predict/Calculate A charging bull elephant with a mass of 5240 kg comes directly toward you with a speed of 4.55 m/s. You toss a 0.150- kg rubber ball at the elephant with a speed of 7.81 m/s.
