1. Understand the Concepts
* Force and Acceleration: Newton's Second Law of Motion states that force (F) equals mass (m) times acceleration (a): F = ma. We can use this to find the car's acceleration.
* Acceleration and Velocity: Acceleration is the rate of change of velocity. We'll use this to find the time it takes the car to stop.
* Stopping Distance: The distance the car travels while decelerating to a stop.
2. Calculate Acceleration
* Given:
* Force (F) = -3000 N (negative sign indicates deceleration)
* Mass (m) = 3000 kg
* Equation: F = ma
* Solve for acceleration (a): a = F/m = -3000 N / 3000 kg = -1 m/s²
3. Calculate Time to Stop
* Given:
* Initial Velocity (v₀) = 10 m/s
* Final Velocity (vf) = 0 m/s (car comes to a stop)
* Acceleration (a) = -1 m/s²
* Equation: vf = v₀ + at
* Solve for time (t): 0 = 10 m/s + (-1 m/s²) * t
t = 10 s
4. Calculate Stopping Distance
* Given:
* Initial Velocity (v₀) = 10 m/s
* Time (t) = 10 s
* Acceleration (a) = -1 m/s²
* Equation: d = v₀t + (1/2)at²
* Solve for distance (d): d = (10 m/s)(10 s) + (1/2)(-1 m/s²)(10 s)²
d = 100 m - 50 m
d = 50 m
Therefore, the stopping distance for the car is 50 meters.
