A block of mass 3.62 kg lies on a frictionless

horizontal surface. The block is connected
by a cord passing over a pulley to another
block of mass 7.8 kg which hangs in the air, as
shown. Assume the cord to be light (massless
and weightless) and unstretchable and the
pulley to have no friction and no rotational
inertia.
Calculate the acceleration of the first block.
The acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s2
Calculate the tension in the cord.
Answer in units of N
