Question

a particle shows distance-time curve as given in this figure.the maximum instantaneous velocity of the particle is around the point​

Answer 1

Answer:

Option (3) C

Explanation:

Instantaneous velocity

v = dS/dt

or, $v= \lim_{\Delta t \to 0} \frac{\Delta S}{\Delta t}$

Now, dS/dt will be maximum when the interval taken for Δt is smaller and the interval for ΔS is bigger

In other words the instantaneous velocity will be maximum for the point where the slope of the Distance-Time curve is maximum

∵ From observation of the curve, at point C, the slope of the distance-Time curve is maximum

∴ at C, the instantaneous velocity is maximum

Answer 2

Answer:

at c the instantaneous velocity is maximum
