You are waiting at a traffic light on Manchester Expressway. At the instant the traffic light runs green, your car (a Toyota Rav4) that has been waiting at an intersection starts ahead with a constant acceleration of 3.17 m/s2. At the same instant a truck (a Ford Ranger), traveling with a constant speed of 20.2 m/s, overtakes and passes you. How far beyond the traffic light do you overtake the truck? Your Answer: Answer

**Problem Statement:**

You are waiting at a traffic light on Manchester Expressway. At the instant the traffic light runs green, your car (a Toyota Rav4) that has been waiting at an intersection starts ahead with a constant acceleration of 3.17 m/s². At the same instant, a truck (a Ford Ranger), traveling with a constant speed of 20.2 m/s, overtakes and passes you. How far beyond the traffic light do you overtake the truck?

**Your Answer:**

[Answer Box]

**Explanation:**

This problem involves understanding and applying the principles of kinematics. Here we have two vehicles starting from the same point but with different motions:

1. The Toyota Rav4 starts from rest and accelerates at a constant rate.
2. The Ford Ranger travels at a constant speed.

We'll need to set up equations that describe the motion of both vehicles and find the point at which the distances covered by the two vehicles are equal.

**Approach:**

1. **Toyota Rav4 (accelerating):**
   - Initial velocity (\( u \)) = 0 m/s (since it starts from rest)
   - Acceleration (\( a \)) = 3.17 m/s²
   - Distance traveled (\( s_{\text{car}} \)) after time (\( t \)) can be found using the equation:
     \[ s_{\text{car}} = ut + \frac{1}{2}at^2 \]
     \[ s_{\text{car}} = 0 + \frac{1}{2} \cdot 3.17 \cdot t^2 \]
     \[ s_{\text{car}} = 1.585 \cdot t^2 \]

2. **Ford Ranger (constant speed):**
   - Constant speed (\( v \)) = 20.2 m/s
   - Distance traveled (\( s_{\text{truck}} \)) after time (\( t \)) is:
     \[ s_{\text{truck}} = v \cdot t \]
     \[ s_{\text{truck}} = 20.2 \cdot t \]

3. **Equating the distances:**
   - Set the distance equations equal to find the time when the Toyota Rav4 overtakes the truck:
     \[ 1.585 \cdot t^2 = 20.2 \cdot t
