Homework Help: Velocity vs displcement graph

  1. Jun 21, 2013 #1
    1. The problem statement, all variables and given/known data
    The graph is as folllows-(SEE ATTACHMENT)
    Q.draw acceleration vs disp. graph.

    2. Relevant equations
    Basic equations of motion, basic calculus

    3. The attempt at a solution
    I have tried to write a linear equation in v and s and then differentiating it w.r.t. to time. but im not sure if this is the correct way to do it. It gives me a positive slope and -ve y intercept.
    Also if there is/are any other ways please do tell

    first write the v-s equation, but do not diffrentiate it with time(as it would add one more variable which is not needed)

    Hint: What is the relation between v,a and s?

    thanks for your reply.
    i have solved the question.
    1 doubt though which extra variable is generated? on differentiation
    v becomes a
    s becomes v
    constant is eliminated

    I thought 't" would create some some problems but thanks it is eliminated. You can also do it using the relation a = v*dv/ds. This was what i was refering to!
