A 45 g mass is attached to a massless spring and allowed to oscillate around an equilibrium according to:

y(t) = 1.3 * sin( 0.6 * t ) where y is measured in meters and t in seconds.

(a) What is the spring constant in N/m?

k = N/m

.162 NO

HELP: You are given m, the mass. What other quantity appears in the equation involving k, the spring constant, and m?

HELP: You are given the equation of motion

y(t) = A * sin( ω * t )

Now can you find the missing quantity?
