1. Samuel kicks a soccer ball across a grassy field and it eventually comes to a stop. If Newton's law of inertia is true, why did the ball stop? 3. In the case of a car crash, the body's inertia will continue to carry it in its initial direction. However, if the person is wearing a seatbelt, in which direction will this force act? Newton's law only applies to objects at rest. A to the right B The mass of the ball is not great enough to have B to the left inertia, upward Friction with the grass applies a net force on the ball causing it to decrease its speed. D downward D Gravity slowed the ball until it came to a stop. 2. Once in orbit, the space shuttle used very little, if any, rocket power to maintain its speed despite traveling over 15,000 mph! How were NASA engineers able to do this? 4. Suppose you pull Nick, who is standing on a skateboard, using a rope at a constant acceleration. Nick's friend, who weighs the same as Nick, then gets on the skateboard too. How is the force you have to apply to the rope affected to maintain the same constant acceleration? The space shuttle is very massive and must burn its rockets at full power to achieve this speed. D The space shuttle was able to use a special coating in order to achieve its fast speed in space. There will be no change to the required amount of force. The amount of force required is slightly increased. Gravity provides the necessary force to keep the space shuttle traveling at a high rate of speed. The amount of force required is doubled. D The speed generated from force of rockets during liftoff O The amount of force required is four-times as great. is maintained throughout the flight since there is no air friction.
