Someone's car will not start, so a friend helps him by pushing it. By pushing as hard as he can for 10 seconds, be makes the car reach a speed of 2ms⁻¹. Calculate the acceleration he has given to the car

$\huge\rm\red{❥AnsWer}$

$\rm\blue{❥Given}$

• The car is at rest .

• therefore its initial velocity is 0

• Time given here is 10 seconds

• Final velocity of the car is 2ms⁻¹.

$\rm\blue{❥To\:find}$

• acceleration of the car = ?

From 1st equation of motion ,

$\rm\green{v=u+at}$

• v = 2 (v means final velocity)

• u = 0 ( u mean initial velocity )

• a = ? ( a mean acceleration)

• t = 10 s ( t means time )

v = u + at

➡️ 2 = 0 + a × 10

➡️ 2 = 0 + 10a

➡️ 2 - 0 = 10a

➡️ 2 = 10a

➡️ 2/10 = a

➡️ a = 0.2 ms²

Therefore , acceleration = 0.2ms²
