Question

The position vector of an object at any time t is given by 3t2i + 6t j+k. Its velocity along y-axis has the
magnitude​

Answer 1

Hi dude....

HERE IS UR ANSWER:

X = 3t² i + 6t j + 1.k

differentiate with respect to time

dx/dt = 6t i + 6j + 0k

we know , dx/dt = velocity

so,

v = 6t i + 6 j + 0.k

hence , velocity along x -axis = 6t

velocity along y-axis = 6

and velocity along z-axis = 0

hence, velocity along y -axis = 6 unit

HOPE THIS HELPS....
