Question

Two boys A and B, pull a book between them with forces depicted in the figure.

(1) Is this a case of balanced forces? Give reason why/why not?

ii) Also calculate the net force and tell the direction of the net force in the event.​

Answer 1

Answer:

$\huge{ \bold{ \blue{b{ \pink{h{ \green{a{ \red{a{ \blue{r{ \pink{a { \green{t{ \orange{2{ \red{4{ \red{1{ \blue{0{ \orange{0{ \pink{1}}}}}}}}}}}}}}}}}}}}}}}}}}}$

Answer 2

• In this chapter, we take major steps toward a discovery and appreciation of the fundamental laws of nature that underlie so much of the bicycle's magical behavior. The primary emphasis is to understand the role of forces in controlling the motion of the two-wheeler. A rationale is developed for the mechanism by which the bicycle offers the most efficient form of human powered locomotion. The force of friction, normally considered a foe to motion, is regarded as a friend. We will learn how friction accelerates the bicycle forward and how this same friction stops the bike when needed. Freewheeling, the ability of the bicycle to joyously coast along with no effort by the rider, is a benefit of inertia—the tendency of an object to remain in motion.
