Question

If a body travels with uniform acceleration $a_{1}$ for time $t_{1}$ and with uniform acceleration $a_{2}$ for a time $t_{2}$ , then the average acceleration is given by
$a_{a v} = \frac{a_{1} t_{1} + a_{2} t_{2}}{t_{1} + t_{2}}$ (Yes/No)

Open in App

Solution

(Refer to Image)
$a_{a v e r a g e} = \frac{area Total}{Total tins}$
$= \frac{a_{1} t_{1} + a_{2} t_{2}}{t_{1} + t_{2}}$
Answer is Yes.
