Questions
Figure shows two blocks, each of mass m. The system is released from rest. If accelerations of blocks
A and B at any instant (not initially) are a1 and a2, respectively, then
.
detailed solution
Correct option is D
Let at any time, their velocities are v1 and v2, respectively.Then v1=v2cosθDifferentiating: a1=a2cosθ−v2sinθdθdtHence, none of them is correct.[Note: Option (a) is correct initially, because initially v2=0]Talk to our academic expert!
