Question

Assuming all the surface to be frictionless acceleration of the block C shown in the figure is:

• A. 8 $m/s^2$
• B. 5 $m/s^2$
• C. 4 $m/s^2$
• D. 6 $m/s^2$

Answer 1

The correct option is C 4 $m/s^2$

Acceleration of block A$=3m/s^2$

Acceleration of block B$=5m/s^2$

Acceleration of block C will be given as,

$a_C=\frac{a_A+a_B}{2}$

$a_C=\frac{3+5}{2}$

$a_C=4m/s^2$

Hence, acceleration of block C$=4m/s^2$
