As a traffic light turns green, a waiting car starts with a constant acceleration of 6.0 m/s^2.At the instant the car begins to accelerate, a truck with a constant velcoity of 21 m/s pass in the next lane.
(a) How far will the car travel before it overtakes the truck?
(b) How fast will the car be traveling when it overtakes the truck?
Calculations (a) :
Car:
Vi = 0 m/s
Vf = ?
Acceleration = 6.0 m/s^2
Truck:
Vi = 21 m/s
Vf = 21 m/s
Acceleration = 0 m/s^2
* in order to figure out (a), the deltaD's of both the car and truck must be equal
- I'm not to sure if the deltaT will be the same but it seems as though the intial time is the same
This is all I know so far; I've been trying to sub in equations but nothing seems to work. Could someone please guide me in the right direction. Thanks :)
