Question

1. Velocity (in m/s) of a particle moving along x-axis varies with time as, v = (10+5t - t?)
At time t =0, x = 0. Find
(a) acceleration of particle at t = 2 s and
(b) x-coordinate of particle at t = 3 s
42​

Answer 1

Step-by-step explanation:

velocity = 10+ 5t -t^2 m/s

we know that acceleration is time derivative of velocity

a = 5 -2t m/s^2

ans of (a)

at t= 2 s

a = 5-2×2 = 1 m/s^2
