Question

A spring is hung vertically and a mass of 290 g is attached to the spring. It is found to deflect 0.15 m.

a. Find the spring constant of this spring. N/m

b. A mass of 500 g is attached to the spring which is stretched a distance of 0.30 m on a horizontal frictionless surface. The spring is released and the mass returns to its equilibrium position. Find the velocity of the mass when it reaches this equilibrium position. m/s

c. The spring is now placed in a vertical position and compressed 0.4 m. A 100 g mass is placed on top of the spring and the spring is released. Find the height to which the mass will go, measured from the starting point. Hint: Select this starting point as the zero point for potential energy. m

Explanation / Answer

a) mg = kx 0.29*9.8 = 0.15*k k = 18.9466667 N/m One Question at a time
