Chapter 6, Problem 52PCE
Driving in your car with a constant speed of v = 22m/s, you encounter a bump in the road that has a circular cross section, as indicated in Figure 6-60. If the radius of curvature of the bump is r = 52m, find the apparent weight of a 67-kg person in your car as you pass over the top of the bump.

A 0.075 kg toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with a constant speed of 4.47 m/s in a horizontal circle of radius 1.28 m, as illustrated in Figure 6-40 (image attached). Find (a) the angle the string makes with the vertical and (b) the tension in the string.
EXAMPLE 5-11 ESTIMATE Gravity on Everest. Estimate the effective
value of g on the top of Mt. Everest, 8850 m (29,035 ft) above sea level
(Fig. 5-20). That is, what is the acceleration due to gravity of objects allowed to
fall freely at this altitude? Ignore the mass of the mountain itself.
APPROACH The force of gravity (and the acceleration due to gravity g) depends
on the distance from the center of the Earth, so there will be an effective value g
on top of Mt. Everest which will be smaller than g at sea level. We assume the
Earth is a uniform sphere (a reasonable "estimate").
SOLUTION We use Eq. 5-5, with r replaced by r = 6380 km + 8.9 km
6389 km
6.389 x 106 m:
(6.67 x 10-11 N-m2/kg²)(5.98 x 1024 kg)
(6.389 x 10° m)
which is a reduction of about 3 parts in a thousand (0.3%).
