Q.
A force represented as show in figure acts on a body having a mass of $16\, kg$. The velocity of the body at $=10 \,s$, if the body starts from rest:-
Laws of Motion
Solution:
Area under $( F - t )$ curve $= M \left( v _{ f }- v _{ i }\right)$
or $50 \times 5+75 \times 5=16\left( v _{ f }-0\right)$
$\therefore v _{ f }=39 \,m / s$
