The velocity of the 9.5 kg object after collision is 5.4 m/s to the left. 1. The velocity of the 2.4 kg object after collision is A. B. C. D. 2. 15 m/s to the right 8.7 m/s to the left 8.0 m/s to the right 6.2 m/s to the left Two carts, each with a spring bumper, collide head-on. At one point during the collision, both carts are at rest for an instant. At that instant, the kinetic energy that the carts originally possessed is almost completely A. B. C. D. lost to friction transformed into heat and sound converted into kinetic energy in the spring bumpers converted into potential energy in the spring bumpers 1 Numerical Response 1. A 1 575 kg car, initially travelling at 10.0 m/s, collides with a stationary 2 250 kg car. The bumpers of the two cars become locked together. The speed of the combined cars immediately after impact is __________m/s. (Record your three-digit answer in the numerical-response section on the answer sheet.) 3. A 115 g arrow travelling east at 20 m/s imbeds itself in a 57 g tennis ball moving north at 42 m/s. The direction of the ball-and-arrow combination after impact is A. B. C. D. 4. 46° N of E 46° E of N 25° E of N 25° N of E In an inelastic collision, the energy that appears to be missing is converted into A. B. C. D. sound and momentum force and momentum sound and heat heat and force 2 Use the following information to answer the next question. Force–Time Graph Force (N) Fmax 0 0.05 0.10 0.15 0.20 Time (s) This graph shows the relationship between the force on a 0.801 kg football and the time a kicker’s foot is in contact with the ball. As a result of the kick, the football, which was initially at rest, has a final speed of 28.5 m/s. Numerical Response 2. The magnitude of the maximum force, Fmax, exerted on the ball during the kicking process, expressed in scientific notation, is a.b × 10c N. The values of a, b, and c are _____ , _____ , a...
