Question

thevelocity of the particle given by equTion v=2t2 +5 find the change in the particle attime interval t1=2s t2=4s and the average acceleration or the instantaneous acceleration t2=4s

Answer 1

$v = 2 {t}^{2} + 5$
$v = 2.4 + 5$
$v = 8 + 5$
$v = 13$
a=?
t=2sec
v=13
$a = \frac{v}{t}$
$a = \frac{13}{2}$
$a = 6.5$
