Question

The figure shows a velocity-time graph of a particle moving along a straight line. Identify the region in which the magnitude of rate of change of velocity $\left|\frac{\Delta v}{\Delta t}\right|$ of the particle is maximum.

• A. $0to2s$
• B. $2to4s$
• C. $4to6s$
• D. $6to8s$

Answer 1

The correct option is C $4to6s$

The slope for the region 4 to 6 seconds is maximum.
Since acceleration equals slope of v-t curve.
Hence, acceleration will be maximum in time interval of 4 to 6 seconds
