Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Dynamics, please solve correctly and understandable.

A girl having a mass of 25 kg sits at the edge of the merry-go-round so her center of mass
G is at a distance of 1.5 m from the axis of rotation. If the angular motion of the platform
is slowly increased so that the girl's tangential component of acceleration can be
neglected, determine the maximum speed which she can have before she begins to slip
off the merry-go-round. The coefficient of static friction between the girl and the merry-
go-round is us = 0.3.
