1) [5] When a ﬁghter pilot makes a very quick turn he can pass out due to the centripetal

acceleration associated with the turn. This happens typically when this acceleration reaches

8g. Consider a pilot ﬂying at 2200 km/h (2.2×103km/h) steering into such a turn. What is

the minimum radius he needs to follow to avoid a black-out?

2) [5] A roller coaster track as shown in the ﬁgure is designed such that a car travels upside

down when at the top. The track has a radius of 25 m. What is the minimum speed the car

has to have at the top to avoid falling out of the track? Start with a free-body diagram and

explain your steps.

## Document Summary

Consider a pilot ying at 2200 km/h (2. 2 103 km/h) steering into such a turn. What is the minimum radius he needs to follow to avoid a black-out: [5] a roller coaster track as shown in the gure is designed such that a car travels upside down when at the top. Start with a free-body diagram and explain your steps. Calculate the gravitational attraction that m2 and m3 exert on m1. Start with a drawing indicating the positions of the masses and the force vectors acting on m1. 2: a car is pushed along a long road that is straight, at, and parallel to the x direction. 2 a t2 f (t) dt = t2 f (t) dt = at + c f (t) = anti-derivative = inde nite integral g = 9. 8 m/s2.
