Explanation / Answer

part a )

T = 2pi*sqrt(m/k)

m = 17/9.8

k = 174

T = 0.627 s

part b)

TE = KE + PE

mg = kx

x = mg/k = 17/174 = 0.0977 m

TE = 2.9 + 1/2 * 174 * (0.0977)^2

TE = 3.73 J

at top most position TE = kx^2/2

x = +0.207m , -0.207 m

for above position = x = 0.1093

part c )

x = 0.3047 m

part d )

from part b)

x = 0.207 m

part e )

TE = 3.73 J
