Question

if the velocity of an objed is increased from 30m/sec to 80m/sec
in 20 sec find its accelerations​

Answer 1

Answer:

a=v-u/t

where v=80

u=30

a=50/20

a=2.5ms^-2

Answer 2

Answer:

${\underline{\red{Given:}}}$

$Velocity=30m/sec$

$Final\:velocity=80m/sec$

$Time\:taken=20\:sec$

${\underline{\orange{To\:find:}}}$

$Acceleration=??$

${\underline{\pink{Taken:}}}$

$Acceleration=\frac{Final\:velocity-Velocity}{Time}$

${\underline{\green{Solution:}}}$

$\mapsto{Acceleration=\frac{80m/sec-30m/sec}{20\:sec}}$

$\mapsto{Acceleration=\frac{50m/sec}{20\:sec}}$

$\mapsto{Acceleration=2.5m/sec}$

${\underline{\blue{Conclusion:}}}$

So , the acceleration is 2.5 m per second.
