In the figure acceleration of A is 1 m/s2 upwards, acceleration of B is 7 m/s2 upwards and acceleration of C is 2 m/s2 upwards. The acceleration of D will be
detailed solution
Correct option is C
Acceleration of pulley PaP=aA+aB2=1+72=4m/s2 (upward) Acceleration pulley Q will be 4m/s2 downwards.aQ=aD−aC24=aD−22⇒aD=10m/s2(↓)Talk to our academic expert!
