Question

Two blocks are attached to the two ends of a string passing over a smooth pulley as shown in the figure. The acceleration of the block will be $\left(inm/s^2\right)(sin{37}^0=0.60,sin{53}^0=0.80)$

• A. 0.33
• B. 0.133
• C. 1
• D. 0.066

Answer 1

The correct option is B 0.133

$a=\frac{m_{2}sin\beta -m_{1}sin\alpha }{m_1+m_2}g\frac{50sin{53}^{\circ }-100sin{37}^{\circ }}{100+50}g=-0.133m/s^2$
