25.1. INTRODUCTION

In the previous chapter, we discussed the

motion of a body, when it is subjected to some external

force. But in this chapter, we shall discuss the motion

of a body, when it is connected by a string to another

body, which is subjected to some external force. A

little consideration will show, that in this case the

velocity and acceleration of both the bodies will be

the same. Now in this chapter, we shall discuss the

following cases :

1. Two bodies connected by a string and pass-
   ing over a smooth pulley.


2. Two bodies connected by a string one of which
   is hanging free and the other lying on a hori-
   zontal plane.
