A student uses a spring to launch a marble vertically in the air. The mass of the marble is 0.002 kg and

when the spring is stretched 0,05 m it exerts a force of 10 N. What is the maximum height the marde can

reach?

    25 m

    Explanation:

    Work to compress spring = gravitational potential energy of marble

    W = PE

    Fd = mgh

    h = Fd / (mg)

    Given F = 10 N, d = 0.05 m, m = 0.002 kg, and g = 10 m/s²:

    h = (10 N) (0.05 m) / (0.002 kg * 10 m/s²)

    h = 25 m
