- In his novel From the Earth to the Moon (1865), JulesVerne describes a spaceship that is blasted out of a cannon, calledthe Columbiad, with a speed of 12,000 yards>s. The Columbiad is900 ft long, but part of it is packed with explosives, so the spaceship accelerates over a distance of only 700 ft. Estimate the acceleration experienced by the occupants of the spaceship duringlaunch. Give your answer in m>s2. (Verne realized that the “travelers would . . . encounter a violent recoil,” but he probably didn’tknow that people generally lose consciousness if they experienceaccelerations greater than about 7g ∙ 70 m>s2.)Suppose you are driving your car on a business trip and are traveling at 30 m/s. Your boss, who is waiting at your destination, expects the trip to take 5.0 h. When you arrive late, your excuse is that the clock in your car registered the passage of 5.0 h but that you were driving fast and so your clock ran more slowly than the clock in your boss’s office. If your car clock actually did indicate a 5.0-h trip, how much time passed on your boss’s clock, which was at rest on the Earth?At noon, Fred is driving south on Highway 1, 50 miles north of its intersection with Highway 2. He is traveling at 40 miles per hour. At noon, Jill is driving west on Highway 2 through its intersection with Highway 1. She is traveling at 30 miles per hour. (a) When will Fred reach the intersection with Highway 2? (b) How far apart will the two cars be at that time? (c) When will the two cars be closest to each other, “as the crow flies”? (d) How far apart will they be at that time?
- Sophia is cruising at 28.0 m/s down Lake Avenue and through the forest preserve. She notices a deer jump into the road at a location 62.0 m in front of her. Ima first reacts to the event, then slams on her brakes and decelerates at -8.10 m/s2, and ultimately stops a picometer in front of the frozen deer. What is Ima's reaction time? (i.e., how long did it take Sophia to react to the event prior to decelerating?Sarah traveled 90 km at a certain speed. In going back, she increased her speed by 10 km/hr. If it took her a total of 10/3 hours, what was her original speed? Explain also. Create an expression to: Sarah traveled 90 km at a certain speed. Create another expression to: In going back, she increased her speed by 10 km/hr.
