Question

A car starts from rest and gains velocity of 20 m/s in 10 seconds. Find its acceleration.
please solve it.

Answer 1

Step-by-step explanation:

u = 0

v = 20 m/s

t = 10 second

a = v-u/t

a = 20 - 0 /20

=20/20

=1 metre per second square

Answer 2

Step-by-step explanation:

QUESTION:

A car starts from rest and gains velocity of 20 m/s in 10 seconds. Find its acceleration.

SOLUTION:

$initial \: velocity (u) = 0 \\ final \: velocity\: (v) = 20 \\ time \: (t) = 10s$

$∴acceleration(a) = \frac{v - u}{t} \\ = (\frac{20 - 0}{10})m {s}^{ - 2} \\ = ( \frac{20}{10})m {s}^{ - 2} \\ = 2m {s}^{ - 2}$

HENCE, acceleration is 2m/s².
