An athlete runs 9 km in 46.9 min, as measured by a friend at rest relative to the Earth. The runner also measures the time with a watch. By how much do the two time measurements differ? (Hint: Use the binomial approximation.)
Homework Answers
there is very small change in
time which can not be detected .Add Answer to:

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?

this is one question but with multiple choice questions,
sorry.
Problem 1 You're in a spaceship in deep space. Your engines are off, and you're far away from any reference points. a) You release a small ball from rest. The ball remains floating at rest in the same position where you released it. What kind of reference frame are you in? Is there any way to tell if you are moving at all? Let's designate your reference frame as S,...
