If the car's speed decreases at a constant rate from 60 mi/hmi/h to 50 mi/hmi/h in 3.0 ss, what is the magnitude of its acceleration, assuming that it continues to move in a straight line?

    The magnitude of the acceleration is 1.2 * 10⁴ mi/h²

    Explanation:

    Hi there!

    The acceleration is defined as the change in velocity in a time:

    a = Δv / Δt

    Where:

    a = acceleration.

    Δv = change in velocity = final velocity - initial velocity.

    Δt = elapsed time.

    In this case:

    Initial velocity = 60 mi/h

    final velocity = 50 mi/h

    elapsed time = 3.0 s

    Let's convert the time unit into h:

    3.0 s · 1 h / 3600 s = 1/1200 h

    Now, let's calculate the acceleration:

    a = Δv / Δt

    a = (50 mi/h - 60 mi/h) / 1/1200 h

    a = - 1.2 * 10⁴ mi/h²

    The magnitude of the acceleration is 1.2 * 10⁴ mi/h²
