Question

The velocity of a particle moving along x axis is given as v=3x.Acceleration of the particle at x=2m is

Answer 1

Answer:

acceleration = rate of change of velocity

dv/dx = d(3x)/dx = 3

acceleration = dv/dt = (double differentiation)

a = dv/dx × Vx. = 3(3x )= 9x

acceleration, at x = 2m

= 9×2 = 18x

Answer 2

Answer:

18x is the right answer xd.....

I hope it helps you......
