Engineers are designing a system by which a falling mass mimparts kinetic energy to a rotating uniform drum to which it isattached by thin, very light wire wrapped around the rim ofthe drum (Figure 1). There is no appreciable friction in theaxle of the drum, and everything starts from rest. This systemis being tested on earth, but it is to be used on Mars, wherethe acceleration due to gravity is 3.71 m/s?.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Engineers are designing a system by which a falling mass m
imparts kinetic energy to a rotating uniform drum to which it is
attached by thin, very light wire wrapped around the rim of
the drum (Figure 1). There is no appreciable friction in the
axle of the drum, and everything starts from rest. This system
is being tested on earth, but it is to be used on Mars, where
the acceleration due to gravity is 3.71 m/s?. In the earth
tests, when m is set to 15.0 kg and allowed to fall through
3.00 m, it gives 350.0 J of kinetic energy to the drum.
