two blocks of masses m and m, with m > m, are connected by a light string. the string passes over a frictionless pulley of negligible mass so that the blocks hang vertically. the blocks are then released from rest. what is the acceleration of the block of mass m ?



Answer :

[(M-m)/(M+m)]g  is the acceleration of the block of mass m.

The correct option is E.

What is acceleration ?

Acceleration is the term used to describe the pace at which speed and direction of velocity vary over time. Even when something speeds up or slows down, it continues to go forward. Motion on the a circle accelerates even while the speed is constant so because direction is always changing. According to our theory, an object's velocity changes when it begins to slow down, and it then starts to accelerate. This item is therefore going backward.

Is acceleration a speed?

We refer to a change in an object's direction or speed as acceleration. The rate at which speed varies is known as acceleration. Please remember that velocity has two parts: speed and direction.
