Question

The velocity of a particle moving along x - axis is given as v=x2−5x+4(in m/s), where x denotes the x-coordinate of the particle in meters. Find the magnitude of acceleration of the particle when the velocity of particle is zero?

Answer 1

Answer:

Given velocity v=x2−5x+4. Acceleration a≡dvdt ... We also know that dxd t≡v ... at v=0 above equation becomes a=0 ...
