A woman stands in a boat at rest on a calm lake. She throws a 10 kg anchor off the front of the boat, which has a mass of 1,000 kg What is the initial momentum of the anchor-boat system?

A)1,000 kg m/s

B)zero because both objects are at rest.

C)1,010 kg m/s

D)10,000 kg m/s

PLEASE HELP!! I don’t understand

B) zero because both objects are at rest

Explanation:

Given the following :

Mass of anchor = 10kg

Mass of boat = 1000kg

Note : both boay and anchor are at rest, this gives a Velocity of zero

The momentum of a body is given as the product of Mass and velocity, that is,

Momentum = mass × velocity

Initial Momentum of anchor-boat system =

(mass of boat× initial velocity of boat) + (mass of anchor × initial velocity of anchor)

Initial Velocities of boat and anchor = 0

Therefore,

Initial momentum = (1000 × 0) + (10 × 0)

Initial momentum = (0 + 0) = 0

This is ecause both objects are at rest.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
