Question

A particle stars moving with acceleration 2 $m/s^2$ Distance travelled by it in $5^{th}$ half second is

• A. 1.25 m
• B. 2.25 m
• C. 6.25 m
• D. 30.25 m

Answer 1

The correct option is B 2.25 m

Given,

Acceleration, $a=2m{s}^{-2}$

Distance travelled in 5th half second = Distance travelled in 2.5 seconds - Distance travelled in 2 seconds $S=0.5a(t{}^{\text{2}}-t{}^{\text{2}})=0.5\times 2\times (2.5{}^{\text{2}}-2{}^{\text{2}})$

$S=2.25m$

Hence, distance traveled is $2.25m$
