Question

If velocity of a particle is given by y = 2t-1 then find the acceleration of particle at t=2s.​

Answer 1

Explanation:

Velocity = 2t -1

acceleration = 2

Answer 2

To find acceleration we should differentiate the velocity:

dv/dt = d(2t-1)/dt

= 2m/s^2

Therefore the acceleration is 2m/s^2.
