To perform an experiment to determine the force constant of a spring, you will need a stand with a boss and clamp, a spiral spring, a meter rule and different weights.
The setup is arranged as shown in the image attached. The natural length of the spring is first recorded. Different weights are added to the spring one after the other and the extension is recorded.
The weight is now plotted on the vertical axis and the extension is plotted on the horizontal axis. The slope of the graph is the force constant of the spring.

Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.
The next step is -748 divide by -11 is 68 m (answer) the pic got cropped sorry
<span>The distance "d" you bike varies directly with the amount of time "t" you bike. Therefore,
d </span>α t
To turn it into equality, we introduce k, proportionality constant.
d = kt
We find the value of k from the given conditions. <span>Suppose you bike 13.2 miles in 1.25 hours.
13.2 = k(1.25)
k = 10.8 miles/our
Therefore the equation would be:
d = 10.8t
It is a linear graph with slope 10.8 and it passes at the origin.</span>
