Question

A ar starts from rest and picks up a velocity of 20m/s in 10 seconds. Calculate the acceleration of the car☺

Answer 1

Answer:10m/s

Explanation:

V-U/t

20-0/10

20/10

10m/s

Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

☯ Given :

Initial Velocity of car (u) = 0 m/s

Final velocity of car (v) = 20 m/s

Time taken by car (t) = 10 seconds

$\rule{200}{1}$

☯ To Find :

We jave to find the acceleration done by the car.

$\rule{200}{1}$

☯ Solution :

We know the formula to find the acceleration.

$\Large{\implies{\boxed{\boxed{\sf{a = \frac{v - u}{t}}}}}}$

Where,

• a is Acceleration
• v is Final velocity
• u is initial velocity
• t is time taken

$\bf{\dag \: \: \: \: Putting Values} \\ \\ \sf{\rightarrow a = \frac{20 - 0}{10}} \\ \\ \sf{\rightarrow a = \frac{2\cancel{0}}{\cancel{10}}} \\ \\ \sf{\rightarrow a = 2} \\ \\ \Large{\implies{\boxed{\boxed{\sf{a = 2 \: ms^{-2}}}}}}$
