Answer: "B" Changing Position
Great Question!
Explanation: <u><em>When a ball bounces to the ground it hits the ground with some energy. The amount of energy with which it hits the ground is kinetic energy. When it comes in the contact with the ground kinetic energy gets converted into potential energy. This potential energy again gets converted into kinetic energy and balls moves again from the ground and bounces multiple times. So, the ball ends up changing position</em></u>

<span>Is the following sentence true or false? Newton's first law does object's mass concentration and its axis of rotation increases, its rotational inertia The bicycle wheels at rest have no angular momentum, and the bicycle will fall over easily.</span><span>

Acceleration = ▵v/▵t
Time = d/v
Fisrt calculate time : ( 118/29 ) = 4 seconds
Then calculate acceleration
A = 29/4 = 7.25 m/s²
Now the force.
Force = mass * acceleration.
F= 1,019 * 7.25
F= 7,387 N
Answer:
I = 97.2 10³⁶ kg m²
Explanation:
The moment of inertia of a body the expression of inertia in the rotational movement and is described by the expression
I = ∫ r² dm
In this problem we are told to use the moment of inertia of a uniform sphere, the expression of this moment of inertia is
I = 2/5 M r²
where m is the mass of the earth and r is the radius of the earth.
Let's calculate
I = 2/5 5.97 10²⁴ (6.38 10⁶)²
I = 97.2 10³⁶ kg m²
