Question

ds
16. At a certain moment of time, acceleration of the
block A is 2 m/s2 upward and acceleration of block
Bis 3 m/s2 upward. The acceleration of block C is
(masses of pulleys and string are negligible)

Answer 1

Answer:

The answer is 7 m/s^2

Step-by-step explanation:

Let's suppose "a" is the acceleration of the pulley.

Given data:

Acceleration of the block A = 2 m/s2 upward  

acceleration of block B = 3 m/s2 upward

Acceleration of pulley = a1 +a2/2

Now assume the acceleration of block C is "x".

Thus  

x-3/2 = 2

x - 3 = 2x2

x-3 = 4

x = 4+3

x= 7m/s^2 downward

Thus the downward accelertaion of bloch c is positive i.e. 7m/s^2

Answer 2

Answer:

The answer is 7 m/s^2

Step-by-step explanation:

Let's suppose "a" is the acceleration of the pulley.

Given data:

Acceleration of the block A = 2 m/s2 upward  

acceleration of block B = 3 m/s2 upward

Acceleration of pulley = a1 +a2/2

Now assume the acceleration of block C is "x".

Thus  

x-3/2 = 2

x - 3 = 2x2

x-3 = 4

x = 4+3

x= 7m/s^2 downward

Thus the downward accelertaion of bloch c is positive i.e. 7m/s^2
