Question

The position of a particle on the x-axis at time t, t>0' is ln t. Find the average velocity of the particle for 1<=t<=e .

Answer 1

(e-1)intergal ln t dt from 1 to e

(e-1) [ 1/e - 1/1]

Answer 2

sorry, all you need is position at t = e - position at t = 1 divided by (e-1)

[ ln e - ln 1/ / (e-1) = 1/(e-1)
