The coefficient of friction between My and the table is 0.20. Assuming the pulley to be massless and frictionless, find the acceleration of the two blocks. nature=rfiQ2PY5raVroh%2BbMUUsUP20IsYCwLTw%2FfMfTJwb%2831%3D&X-Blackboard-Client-Id=449440&X-Blackboard-53 53zyklcOZqvXQ7VFpLF4qCkCn1RZR1NVgsQJdIW4jYZU9IHMKhB955FDMYcuTNADJcBfOcXIlvLSnXOMdG6zYy15j9mNeCoJSpu st&X-Amz-Expires=21600&X-Amz-Credential=ASIAZH6WM4PLRM585WDE%2F20231006%2Fap-southeast-1%2Fs3%2Faws4_rec 1.76 m/s2 B 5.36 m/s2 3.10 m/s2 6.70 m/s2
