  • Calculating Stopping Distance: A Physics Problem Solved
    Here's how to solve this problem:

    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.
