Homework Statement
A car and a truck are heading directly toward one another on a straight and narrow street, but they avoid a head-on collision by simultaneously applying their brakes at t=0 . The resulting velocity-versus-time graphs are shown in the figure .
What is the separation between the car and the truck when they have come to rest, given that at t = 0 the car is at x = 24 and the truck is at x = -44 ? (Note that this information determines which line in the graph corresponds to which vehicle.)
Homework Equations
xf = xi + 1/2 (vf + vi)[tex]\Delta[/tex]t
The Attempt at a Solution
xcar = 25 m + 1/2 (0 + 10 m/s)(2.5s) = 36.5
xtruck = -44 + 1/2 (0 - 15 m/s)(3.5s) = -70.25
xtruck - xcar = -33.75 m?
