Homework Statement
A car is stopped at a red traffic light. At the instant the traffic light turns green, the car
starts to move forward with a constant acceleration of 3.20 m/s2. At the same time as the
light turns green, a truck traveling in the same direction with a constant speed of 20.0
m/s, overtakes and passes the car.
How far beyond its starting point does the car overtake the truck?
So, for the car we have:
- initial velocity = 0
- acceleration = 3.20
for the truck we got:
- final velocity = 20.0
- acceleration = 0
Homework Equations
x-x. = v. t + 1/2 a t^2
v = v. + a t
v^2 = v.^2 + 2 a (x-x.)
The Attempt at a Solution
I really have no clue on how to deal with this as i don't have time or final velocity for the car, a lot of missing information here and i really don't know how to approach to the answer.
I just need help please.
