Question

The displacement x of a partical along x-axis is given by x=3 +8t +7t (sq) obtain it's velocity and acceleration at t =2s

Open in App

Solution

x =x=3 +8t +7t^2

Assuming that you have the basic knowledge of differentiation

Velocity = dx/dt = 8 + 72t

At t=2sec

Velocity = 8+722 = 36m/s

Acceleration = dv/dt = 14m/s2 constant for all t
