A solid wood door 1.00 mm wide and 2.00 mm high is hinged along one side and has a total mass of 43.0 kgkg . Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.600 kgkg , traveling perpendicular to the door at 14.0 m/sm/s just before impact.

A) Find the angular speed of the door. B) Does the mud make a significant contribution to the moment of inertia?

0.290055248619 rad/s

Explanation:

r =

m denotes the mass

v = Velocity = 14 m/s

Moment of inertia of the door

Angular momentum of the mud

As the angular momentum is conserved we have

The angular speed of the door is 0.290055248619 rad/s

The mud has a mass 0.6 kg it will not have a significant on the door which is 43 kg. The door is significantly heavier than the mud.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
