Question

derive the above problem
​

Answer 1

Answer:

Acceleration is defined as the velocity with respect to time..(or Acceleration is defined as the change in velocity).

Velocity is defined as the displacement with respect to time...(or velocity is the change in displacement)

Explanation:

As the acceleration is the velocity w.r.to time, means dv/dt.Since it is given that velocity,V=dx/dt.

therefore substitute( v=dx/dt) in dv/dt. then get the answer as acceleration is the second derivative of displacement.therfore it is d2x/dt2
