**Unformatted text preview: **Quiz 1. Physics 132. Jan/18/08 Name A mass of 100g is hung from a vertical spring and causes the spring to stretch by 10 cm.
a) what is the spring constant? (2pts). If the mass is now displaced 1 cm below the
equilibrium position (take this as y=-1 cm) and released b) What is the resulting frequency
of oscillation? (3pts). c) Write an equation of the form y = A sin(a)t + ¢) that describes the
motion of the mass where you can take t=0 as the time when the mass released (4pts). d) At which point (or points) of the motion is the speed of the mass at its maximum? (1 pt) 3 : 9‘? WIS-L {Wazoo/(9 Ay=l0m ’,lM at) F=~l<y = 7%
