**6: On Neil deGrasse Tyson’s reboot of *Cosmos*, he stands at the edge of an auditorium stage holding a bowling ball suspended by a steel cable. He releases the ball from rest while standing motionless and watches it return to the point depicted below. Why is he in no danger?**

**A) Neil has a hard nose so he won’t get hurt.**
**B) The total mechanical energy in the system is fixed when he releases the ball. The bowling ball stops at the point in question because it would require extra energy for the ball to hit his nose.**
**C) Gravity and tension point in opposite directions, so the bowling ball keeps moving at constant velocity. With no net force, Neil is in no danger.**
**D) Neil is using “The Force” to control the movement of the bowling ball with his mind.**

**7 & 8: Three cars (car F, car G, and car H) are moving with the same velocity when each driver suddenly slams on the brakes, locking the wheels. The most massive car is car F, the least massive is car H, and all three cars have identical tires.**

You are the pilot of a spacecraft intended for travel at very high speeds. Before leaving you measure the spacecraft to be 31.4 m long and have a mass of 5.28 x 104 kg. During your travel, you pass a planet and exchange information with an observer on the planet. You are told that your spacecraft has been measured to be 28.6 m long. a. How fast is your spacecraft travelling with respect to the planet? b. You are told there is a nearby planet that is stationary with respect to the first planet. The observer on the first planet says it will take you 25 s to reach the nearby planet. How far away does your co-pilot on the spacecraft say the nearby planet is? c. How much energy was required to accelerate your spacecraft to this speed?

The Starship Enterprise returns from warp drive to ordinary space with a forward speed of 51 km/skm/s . To the crew's great surprise, a Klingon ship is 140 kmkm directly ahead, traveling in the same direction at a mere 30 km/skm/s . Without evasive action, the Enterprise will overtake and collide with the Klingons in just about 6.7 ss . The Enterprise's computers react instantly to brake the ship. What magnitude acceleration does the Enterprise need to just barely avoid a collision with the Klingon ship? Assume the acceleration is constant.
