Question

Q8. A car accelerates from rest to a speed of 20m/s in 50 seconds.
What is the acceleration of the car in m/s? {Help ME}​

Answer 1

Answer:

U = 0

v = 20m/s

t = 50 sec

$acceleration \: = \frac{v - u}{t}$

a = 20 – 0/50

a = 20/50 = 0.4m/s²

Answer 2

$\mathcal{\huge{\underline{\underline{\pink{Solution:-}}}}}$

We know that,

A = $\dfrac{v-u}{t}$

Where,

• v = 20
• u = 0
• t = 50

▶ A = $\dfrac{20-0}{50}$m/s²

▶A = $\dfrac{20}{50}$m/s²

▶A = $\dfrac{2}{5}$m/s²

▶A =$\cancel{\dfrac{2}{5}}$m/s²

▶A = 0.4 m/s²

✒The acceleration of the car is 0.4 m/s².
