A pendulum on a grandfather clock is supposed to oscillate once every
2.00 s, but actually oscillates once
every 1.99 s. How much must you
increase its length to correct its
period to 2.00 s?
(Unit = m)

be subject to a force andchange its motion

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
