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?
