Question

The initial velocity of a car is 20 m/s and the final velocity is 30 m/s .lf it

takes 2 s to attain this velocity, then what would be it’s acceleration?​

Answer 1

Answer:

acceleration=final velocity- initial velocity/time

= 30-20/2

= 10/2

= 5 m/s²

Answer 2

$\bold u = 20~m/s$

$\bold v = 30~m/s$

$\bold t = 2~s$

$\bold { v = u + at } \\\\\ \implies 30 = 20 + 2a \\\\\ \implies 30 - 20 = 2a \\\\\ \implies \bold{a} = \frac {10}{2} = 5~m/s²$
