What exponent did I drop? I'm confused...
So i guess i should change everything to m?
you said not to forget units on this part. Are the units going to be N/mkg ?
Homework Statement
A block of unknown mass is attached to a spring of spring constant 6.7N/m and undergoes simple harmonic motion with an amplitude of 7.8 cm. When the mass is halfway between its equilibrium position and its max endpoint, its speed is measured to be 38.5 cm/s.
