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
