D	1	1.5	2.1059	36	5.30		d	1	1.5	2.0099	1.5	0.22

This is the data.

T[s] and H[cm] are observed values.

E[J] is the calculated value. Formula for E[J] = mgh = (M)*(9.81)*(H*0.01)

Question

What is the momentum of the pendulum at the highest position? What is the momentum of the pendulum at the lowest position? Determine if the momentum is conserved or not. If not, explain why it is not conserved.
