Question

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?

Answer 1

25 m

Step-by-step explanation:

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. Therefore, the maximum height the marde can reach is 25 m.

Answer 2

25 m

Step-by-step 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
