Answer 1

A body of 200g is set to oscillate in an ideal spring. Knowing he performs two oscillations in 1 second, we can say that the spring constant is worth:

a)
32 N/m
b)
15 N/m
c)
40 N/m
d)
25 N/m
e)
8 N/m

Answer 2

if a body of mass m oscillates on an ideal spring with spring constant k, then the frequency is given by
\[f=\frac{ 1 }{ 2 \pi }\sqrt{\frac{ k }{ m }}\]
which can fairly easily be derived using Newton's second law and the assumption of an oscillatory motion
Rearrange this equation to find k in terms of f and m

Answer 3

could teach me step by step?

Answer 4

multiply both sides by 2pi
square both sides
multiply both sides by m
