Heather in her Corvette accelerates at the rate of (3.40ihat- 2.00jhat) m/s2, while Jill in her Jaguar accelerates at (1.00ihat + 3.40jhat) m/s2. They both start from rest at the origin of an xy coordinate system. Determine the following after 5.50 s.
(a) What is Heather's speed with respect to Jill?


(b) How far apart are Heather and Jill?


(c) What is Heather's acceleration relative to Jill?
( ___ihat + ____jhat) m/s2
