Physics kinematics

  1. Sep 9, 2005 #1
    Jill has just gotten out of her car in the grocery store parking lot. The parking lot is on a hill and is tilted 3 degrees. Fifty meters downhill from Jill, a little old lady lets go of a fully loaded shopping cart. The cart, with frictionless wheels, starts to roll straight downhill. Jill immediately starts to sprint after the cart with her top acceleration of 2.0m/s^2

    how far has the cart rolled before jill catches it.

    i was thinking having a kinematics equation for both, and then solving one of them for a variable that i could substitute into the other equation....yes?

    yes time t will be perameter.

    which kinematics equation should i use, and will it be the same for both of them? i cant do much without velocities :confused:

    what is the significance of 3 degrees because they already gave us the acceleration, is this the accel of the cart?
