Question

if v varies directly as t and v = 19.6 when t =2 , find v when t =3

Answer 1

If v varies directly as t then v/t = k.

Given, v = 19.6 , t = 2

Now, K = 19.6/2=9.8

At the same way,

v/3 = 9.8

v = 9.8*3 = 29.4

Hope helped!

Answer 2

If v varies directly with the..

Then v/t=k..
19.6/2= k= 9.8..

Now

9.8=V/3
V=9.8×3=29.4...
