Impulsive Forces in Collision

Acceleration ...

Question

Acceleration versus time graphs for object are shown below. Explain change in velocity during the interval?

Open in App

Solution

As we know,
Area under the $a - t$ graph gives the change in velocity.
As per the given graph, there is an exponential decrease in velocity so, area under the curve will be less than $\frac{1}{2} t_{\circ} a_{\circ}$ .
Area under the curve $< \frac{1}{2} t_{\circ} a_{\circ}$
Final answer: Area under the curve $< \frac{1}{2} t_{\circ} a_{\circ}$
