1. A 5kg block, resting on a rough horizontal
Surface is connected by light in extensible String over a light friction less pulley to a
second block of mass 3kg hanging vertically.
An applied force of f acting on the
5 kg block is 24 N and
the coefficient of kinetic friction
between the 5kg and the surface is 0.2 . The 5kg block accelerates to the left.

a) Calculate the acceleration of the blooks.
b) Calculate the tension T​

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
