Jill in her Jaguar accelerates at? Heather in her Corvette accelerates at the rate of (3.10 - 2.00) m/s2, while Jill in her Jaguar accelerates at (1.00 + 3.10) m/s2. They both start from rest at the origin of an xy coordinate system. Determine the following after 3.00 s.

(a) What is Heather's speed with respect to Jill? in m/s
b)How far apart are Heather and Jill?in m
(c) What is Heather's acceleration relative to Jill? in i+j form

Please help me. I was assigned this problem for physics homework and do not understand how to do it. I'm worried because we have a test next week. If you could please explain how to do this step by step I'd really appreciate it. Thanks in advance.
