help i speed time graph pls

help i speed time graph pls

Speed time .. hmm Speed-Time .. Integrate the speed equation to get the distance and differentiate the speed equation to get the gradient (acceleration).

there is a formula no?what is it

 

[syed1995]

there is a formula no?what is it

Differential of Displacement with respect to time = Speed
Differential of Speed with respect to time = Acceleration
Integration of Acceleration = Speed
Integration of Speed = Displacement

(u-v)/t

can any one tell me all formulaes related to i j components in r.v

(u-v)/t

also to draw graph there is curves

crazy pic u got;now tell me pls how to increase speed when aswering

LOL my pic is crazy ..

 

[AlphaBeta]

does any one hav examiners tips

some one ans question?????

 

[guitarist112]

how do we find the velocity in the form of i and j vectors when we are given the speed and the position vector!!

if some one ans my question it would have contained ur ans

How will we do Q9 part2?

 

[HarisLatif]

Differential of Displacement with respect to time = Speed
Differential of Speed with respect to time = Acceleration
Integration of Acceleration = Speed
Integration of Speed = Displacement

(u-v)/t

should we learn other formulas of kinematics like v=u+at and s=ut+1/2at^2 ?? please tell these are in the book under the topic equation of motion with constant acceleration. but i never used them in the pastpapers. it's urgent

 

[HarisLatif]

how do we find the velocity in the form of i and j vectors when we are given the speed and the position vector!!

to find that you must have a direction too of the speed which is usually given in the question. By using that form a right angled triangle and find the i and j components. see the example of question which came in may june 2008.

As you have found the derivative in the first part now integrate it separately and equate it to the original equation then solve.

how do we integrate separately?
