(a) The distance time graph of a body makes an angle of `30^(@)` with time axis, Figure. What is its velocity ?
(b) If the same makes an angle of `30^(@)` with distance axis, Figure, what is the velocity of the body ?

Text Solution

Verified by Experts

(a) `v = tan 30^(@) = (1)/(sqrt(3)) = 0.577 m//s`.
(b) In this case, angle with time axis `= 90^(@) - 30^(@) = 60^(@)`. `:. v =tan 60^(@) = sqrt(3) =1.732 m//s`
