Question

Lisa in her Lamborghini accelerates at the rate of (2.40\hat{i} - 2.20\hat{j}) m/s², while Jill in her Jaguar accelerates at (4.80\hat{i} + 2.00\hat{j}) m/s². They both start from rest at the origin of an xy coordinate system. After 5.00 s, find the following. (a) What is Lisa's speed with respect to Jill? m/s (b) How far apart are they? m (c) What is Lisa's acceleration relative to Jill?

Step 1

00 s in her Lamborghini. Given that Lisa's Lamborghini accelerates at a rate of 22.20 m/s, we can use the formula for calculating speed with constant acceleration: \[v = u + at\] where: v = final velocity u = initial velocity a = acceleration t = time In this Show more…
