Question

The displacement s of a moving point in a straight line is given by s=2t2+3t-5 and s is in cm and t is in s then its average velocity

Answer 1

${ \green{ \underline { \underline{ \huge \mathfrak \red{given}}}}}$

s = 2t²+ 3t - 5

${ \green{ \underline{ \huge{ \mathfrak \red{formula}}}}}$

$v \: = \frac{ds}{dt}$

${ \green{ \underline{ \huge \mathfrak \red{solution}}}}$

${ \huge{ {2t}^{2} + 3t - 5}}$

${ \huge{4 + 3}}$

${ \green{ \huge{initial \: velocity \: = 0}}}$

${ \huge{ 4(0) + 3}}$

${ \huge{ 3}}$
