8) Dave is driving his Civic (car A) at 45mi/h (in a 30 zone) up to an intersection and
notes that he passes through the intersection 3 seconds after a classic Ford
Mustang (car B) passed through the intersection doing the speed limit as shown.
Assuming that there is no acceleration of either car, determine (a) the relative
velocity of car B with respect to car A, (b) the change in position of B with respect to
A during a 4-s interval, (c) the distance between the two automobiles 2s after A has
passed through the intersection.

Expert Solution

Step 1: Given Data:

Dave is driving his Civic (car A) is : $open vertical bar V with rightwards arrow on top subscript a close vertical bar equals 45 space m i n divided by h r$

Dave is driving his Civic (car B) is : $open vertical bar V with rightwards harpoon with barb upwards on top subscript B close vertical bar equals 30 space m i n divided by h r$

Given angle is: $theta equals 70 to the power of degree$

Determine:

(a) the relative velocity of car B with respect to car A

(b) the change in position of B with respect car to A during a car 4-s interval
