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.What will be the acceleration of the particle when the velocity of the particle is 0? 

Options

A.0 m/s2
B.2 m/s2
C.3 m/s2
D.None of these

Solution

For v = 0, x = 1, 4 and a = v
so a|x = 1 = 0 × = 0 ; a|x = 4 = 0 × = 0
