Answer:
The value is
Explanation:
From the question we are told that
The diameter of each wheel is
The mass of the motorcycle is
The rotational kinetic inertia is
The mass of the rider is
The velocity is
Generally the radius of the wheel is mathematically represented as
=>
=>
Generally from the law of energy conservation
Potential energy attained by system(motorcycle and rider ) = Kinetic energy of the system + rotational kinetic energy of both wheels of the motorcycle
=>
=>
Here is the angular velocity which is mathematically represented as
So
Here
=>
Answer:
B. The image is right-left reversed and about as far away from the mirror as the reflected object.
Explanation:
A plane mirror is used in several ways in our life, from the mirror that we have on the bathroom to the mirrors we use on cars, the main difference is that the mirror reflects the image reversed on the Vertical axis, which means that the left is the right and the right is the left, a mirror also protrays objects at a certain distance, about as far away from the mirror as the reflected object but they are actually closer in real life.
