A mass suspended on a spring will exhibit sinusoidal motion when it moves. If the mass on a spring is 85 cm off the ground at its highest position and 41 cm off the ground at its lowest position and takes 3.0 s to go from the top to the bottom and back again, determine an equation to model the data.

Question

anonymous · Answer

.   a= 85-41/2 = 22

       d= 85+41/2= 63


 b= 2π/ 3.0= 2.09

c=360/3.0= 120      y= 22sin[2.09(x-120)]+ 63
Can anybody tell me if it is right.
