A body is projected with velocity 19Â·6 m/s in horizontal direction. After what time the horizontal and vertical component of velocity will be the same?

Given, that the body is projected in the horizontal direction.Â

So, we haveÂ

Now, the horizontal component of velocity at any instant is given by,Â

Â

Vertical component of velocity is,Â

Â

Since, horizontal and vertical component of velocity is the same, we have

Â  Â  Â  Â  9.8 t = 19.6

i.e., Â  Â  Â  Â t = 2sÂ
