To solve this problem we will use the concepts related to energy conservation. Both potential energy, such as rotational and linear kinetic energy, must be conserved, and the gain in kinetic energy must be proportional to the loss in potential energy and vice versa. This is mathematically
Where,
m = mass
v = Tangential Velocity
= Angular velocity
I = Moment of Inertia
g = Gravity
Replacing the value of Inertia in a Disk and rearranging to find h, we have
Replacing,
Therefore the height of the inclined plane is 5.6m
27.5 because of you divide the 55miles with the time you get your velocity which is the speed.
It would have 96 because protons equal electrons
Newton's second law is the hardest to describe as it is about momentum (F = ma), and a lot of people don't know the concept of momentum.
Newton's first law of motion:- every object moves in a straight line unless acted upon by a force.
Newton's 2nd law of motion:-the acceleration of an object is directly proportional to the net force exerted and inversely proportional to the item's mass. Newton's 2nd law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
Newton's 3rd law of motion:- For every action, there's an equal and opposite reaction.
