crash
In a friendly game of chicken, Batman has a starting distance of 158.19m in front of
Lightning McQueen. Both cars start with the same speed of 104.42 km/h, and both
cars accelerate at constant rates towards one another (both speed up). Knowing that
Lightning accelerates at 4.43 m/s^2 and Batman accelerates at 4.32m/s^2,
Determine the position, in meters, that they crash.
Given: {xo, vo, al, aB} = { 158.19, 104.42, 4.43, 4.32 }
Find:
• Batman has a starting distance of 158.19m in front of Lightning McQueen
•
Both cars start with the same speed of 104.42 km/h (velocity towards one
another, think through sign)
Lightning speeds up with acceleration of 4.43 m/s^2
Batman speeds up with acceleration of 4.32m/s^2
• The position, in meters, that they crash = ##.m (measured from Lightning's
starting position)
