There is a mass on a spring of 4 kg. The spring constant is 300 Nm. The spring is laying on a horizontal surface. (F=39.2 N)
I need to find:
1. the amplitude if the force is stretching the spring to its maximum displacement, and
2. the velocity of the object at a distance of 0.10 m from the mean position.
To find x, I used F=kx. 39.2=300x, so x=0.13 meters. Would that be the maximum displacement?
I do not know how to find the mean position of the spring. I know the spring has maximum velocity at the mean position when in motion, and I know that the spring also has maximum potential energy at the mean position when stationary.
Can someone give me a push in the right direction? Thanks!
