Question

A particle moves along a parabolic path y= 9x2 in such a way that the Xcomponent of velocity remains constant and has a value 1/3 m/s. Then, find the y component of velocity of the projectile. ​

Answer 1

Answer:

1. answer is 2j m/s∧2

Explanation:

given that velocity along x axis is 1/3

ie, dx/dt= 1/3

dy/dt= 9×2xdx/dt

        =18x× 1/3

        =6x

since we need accleration

d∧2y/dt∧2 = 6×dx/dt

                  6×1/3

                   =2 m/s∧2
