Chapter 2: Q10. (page 43)

Every year, the earth travels about 109km as it orbits the sun. What is the earth’s average speed in km/h?

Short Answer

Expert verified

The earth’s average speed is 1.14×105kmh.

Step by step solution

01

Step 1. Calculation of the total hours in one year

The earth’s orbit is a two-dimensional plane in which it rotates around the sun. The earth takes 365 days to complete one complete cycle in its orbit.

Given data.

The traveled distance of the earth in a year is 109km.

Now, you know that there are 365 days in a year and 24 hours in a day. Then,

1year=365day=365day×24hour1day=8760hour

02

Step 2. Calculation of average speed

Now, you know that

Averagespeed=TotaldistanceTotaltime=109km8760h=1.14×105kmh

Therefore, the earth’s average speed is 1.4×105kmh.

A car slows down uniformly from a speed of 28.0 m/s to rest in 8.0 s. How far does it travel in this time?

A light plane must reach a speed of 35 m/s for takeoff. What length of a runway is needed if the (constant) acceleration is 3.0 m/s2?

An automobile traveling at 95 km/h overtakes a 1.30 km long train traveling in the same direction on a track parallel to the road. If the train’s speed is 75 km/h, how long does it take for the car to pass it, and how far will the car have traveled in this time? See Fig. 2-36. What are the results if the car and the train are traveling in opposite directions?

You drop a rock off a bridge. When the rock has fallen 4m, you drop a second rock. As the two rocks continue to fall, what happens to their velocities?

(a) Both increase at the same rate.

(b) The velocity of the first rock increases faster than the velocity of the second.

(c) The velocity of the second rock increases faster than the velocity of the first.

(d) Both velocities stay constant.

A stone is thrown vertically upward with a speed of15.5m/sfrom the edge of a 75.0 m high cliff (Fig. 2–48).

(a) How much later does it reach the bottom of the cliff?

(b) What is its speed just before hitting?

(c) What total distance does it travel?
