Q123 / 160 · TS EAMCET 2022 (18 Jul Shift 1) · Physics

A body starts from the rest and acquires a velocity of $10 m s^{- 1}$ in $2 s$ . What is the acceleration of the body and the distance travelled

Correct answer
A
$5 m s^{- 2}$ and $10 m$
B
$5 m s^{- 2}$ and $5 m$
C
$5 m s^{- 2}$ and $6 m$
D
$6 m s^{- 2}$ and $5 m$

Solution

For constant acceleration we can write,
$v = u + a t \Rightarrow 10 = 0 + a \times 2 \Rightarrow a = 5 m s^{- 2}$
Now for displacement,
$s = u t + \frac{1}{2} a t^{2} = 0 + \frac{1}{2} \times 5 \times 2^{2} = 10 m$

Hence, the correct answer is option: 'A'.
