Multiple-Concept Example 4 deals with a situation similar to that presented here. A marble is thrown horizontally with a speed o
f 17.1 m/s from the top of a building. When it strikes the ground, the marble has a velocity that makes an angle of 39 ° with the horizontal. From what height above the ground was the marble thrown?

Answer:
Spring constant, k = 24.1 N/m
Explanation:
Given that,
Weight of the object, W = 2.45 N
Time period of oscillation of simple harmonic motion, T = 0.64 s
To find,
Spring constant of the spring.
Solution,
In case of simple harmonic motion, the time period of oscillation is given by :
m is the mass of object
m = 0.25 kg
k = 24.09 N/m
or
k = 24.11 N/m
So, the spring constant of the spring is 24.1 N/m.
