Impulse and Momentum – The Linear Impulse-Momentum Principle
Exp. 2:
A 2 − particle moves in the vertical − plane under the action of
its weight and a force which varies with time. The linear momentum
of the particle in . is given by the expression
where is the time in seconds.
Determine:
and its magnitude for the instant when = 2 sec.
