Question

An archer pulls her bowstring back 0.400 m by exerting a force that increases uniformly from zero to 200 n. (a) what is the equivalent spring constant of the bow

Answer 1

Spring force formula is:

`F=kx`

Where
F = force
k = spring constant
x = displacement from initial position

We have information:
F=200N
x=0.4m
k=?

400=k*0.4
k=1000N/m
