Homework Help: Integrated and got position vector

  1. Oct 15, 2005 #1
    3. A tennis ball is served horizontally from 2.4 m above the ground at 30m/sec
    a) Find its velocity (V) at any time t seconds
    b) Find its position vector (r) at any time t second

    a) v= 30i - gtj
    b) i integrated and got position vector as
    p= 30ti(2.4-.5gt^2)j

    is that it?

    I assume you meant 30ti+ (2.4- .5gt^2)j. If that is so, yes, that's correct.
