Question

A car moving with velocity which is measured each second and the data is recorded as per the table below.

Velocity Time
$0$ $0$
$2m/s$ $1s$
$4m/s$ $2s$
$6m/s$ $3s$
$8m/s$ $4s$
If the object stops accelerating at $4s$ when its speed is $8m/s$, Find out the distance it will travel between $4s$ and $7s$ .

• A. $8m$
• B. $16m$
• C. $18m$
• D. $24m$
• E. $32m$

Answer 1

The correct option is D $24m$

Speed of the car when its acceleration is zero $v=8$ m/s

Time of constant speed $t=7-4=3$ s

Thus distance traveled during constant speed $S=vt=8\times 3=24$ m
