Situational problems need physical insight
that is introduction of physical laws and some symbols to compare the mathematical
results obtained with practical values To solve many problems faced by us, we need a
technique and this is what is known as mathematical modelling Let us consider the
following problems:
(i)
To find the width of a river (particularly, when it is difficult to cross the river) (ii)
To find the optimal angle in case of shot-put (by considering the variables
such as : the height of the thrower, resistance of the media, acceleration due to
gravity etc
