Question

An object undergoes an acceleration of 4m/s'2 starting from rest .find the distance travelled in 2second

Answer 1

GivEn :

• Acceleration, a = 4 m/s²

• Initial velocity, u = 0m/s

• Time taken, t = 2 sec

To find :

Distance travelled in 2 sec.

SolutioN :

We're given with the certain values of Acceleration, initial velocity, & time taken to travel the distance.

We can solve this question using the kinematic equations.

By using the 2nd kinematic equation :

$:\implies\sf S = ut + \dfrac{1}{2} at^2$

$:\implies\sf S = 0 \times 2 + \dfrac{1}{2} 4 \times 2^2$

$:\implies\sf S = \dfrac{1}{2} \times 4 \times 2^2$

$:\implies\sf S = 2 \times 2^2$

$:\implies\sf S = 2 \times 4$

$:\implies\sf { \boxed{ \frak{ \green{S = 8 \: m}}}}$

$\therefore$ Distance travelled in 2 sec is 8 m.
