Question

Tell where velocity is maximum[at "t2" or "t1"] in each case: -
Pleas help:)

Answer 1

Please help:)

Answer 2

Hi there.
Do you know what is velocity in terms of displacement?

Answer 3

\[v = dx/dt\]
Velocity is rate of change of displacement w.r.t time.
Now that you know that all you have to do is compare the slopes of your given examples.

Answer 4

ya:)\[\LARGE{v=\frac{dx}{dt}}.\]

Answer 5

k!

Answer 6

I'll do the first.
At t1.
The slope of the tangent at t1 is positive. At t2 it's negative.
So obviously v at t1 > v at t2.

Answer 7

K!

Answer 8

so in second one at both time, velocities are equal?

Answer 9

Yeah. Good :)

Answer 10

& in 3rd one velocity at t2 is greater?

Answer 11

Yeah.

Answer 12

& last 4th one at t1 is greater?

Answer 13

Yes. Well done :)

Answer 14

thanx a lot:)
