Question

Two masses of 4kg and 5 kg are connected by a string passing through
a frictionless pulley and are kept on a frictionless table as shown in the
figure. The acceleration of 5 kg mass is
(1) 49 m/s2
(2) 5.44 m/s2
(3) 19.5 m/s2
(4) 2.72 m/s2​

Answer 1

m1 =:- 4kg....

ME :- 5kg....

g:-. 10m/s^2

$a = \frac{m2g}{m1 + m2}$

$\frac{5g}{9}$

put the value......

$\frac{5 \times 10}{9}$

$\frac{50}{9}$

$5.555........m {s}^{2}$
