Chapter 6: Q.23 (page 155)

The earth is 1.50脳1011mfrom the sun. The earth鈥檚 mass is 5.98脳1024kg, while the mass of the sun is 1.99脳1030kg. What is earth鈥檚 acceleration toward the sun?

Short Answer

Expert verified

The earth acceleration towards sun is5.9脳10-3m/s2

Step by step solution

01

Content Introduction

For Newton's gravity law, the expression of gravitational force is

Fg=Gmemsr2

Here meis mass of earth, msmass of sun, G is universal gravitational constant and r is the distance between sun and earth.

The net force acting between sun and earth is equal to gravitational force.

Therefore, from Newton's second law of motion

ae=FGme

Combining the expression of acceleration and expression of gravitational force,

ae=Gmsr2

02

Content Explanation

Substitute the values in the above formed expression

ae=(6.67脳10-11N.m2/kg2)(1.99脳1030kg)(1.50脳1011m)2ae=5.9脳10-3m/s2

A football coach sits on a sled while two of his players build their strength by dragging the sled across the field with ropes. The friction force on the sled is 1000N, the players have equal pulls, and the angle between the two ropes is 20掳. How hard must each player pull to drag the coach at a steady2.0m/s?

Boxes A and B in FIGURE Q6.13 both remain at rest. Is the friction force on A larger than, smaller than, or equal to the friction force on B? Explain

A rifle with a barrel length of 60cm fires a 10g bullet with a horizontal speed of 400m/s. The bullet strikes a block of wood and penetrates to a depth of 12cm.

a. What resistive force (assumed to be constant) does the wood exert on the bullet?

b. How long does it take the bullet to come to rest?

Five balls move through the air as shown in FIGURE Q6.17 All five have the same size and shape. Air resistance is not negligible. Rank in order, from largest to smallest, the magnitudes of the accelerations aa to ae. Some may be equal. Give your answer in the form a7b=c7d7eand explain your ranking.
