The boxes of masses 2kg and 8kg are connected by a massless string passing over smooth pulleys. Calculate the time taken by box of mass 8kg to strike the ground starting from rest. (use g=10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
D
(m 1 g − 2T) = m 1 a − (1)
T − m 2 g = m 2 (2a)
t=0.4sec
