The statement “When
an object is in orbit, it is falling at the same rate at which the Earth is
curving” is true. The speed of a satellite orbiting the earth depends only on
the mass of the earth and the mass of the satellite.
Answer:
Explanation:
= Initial momentum of the pin = 13 kg m/s
= Initial momentum of the ball = 18 kg m/s
= Momentum of the ball after hit
= Angle ball makes with the horizontal after hitting the pin
= Angle the pin makes with the horizotal after getting hit by the ball
Momentum in the x direction
Momentum in the y direction
The pin's resultant velocity is
The pin's resultant direction is below the horizontal or to the right.
Answer: acceleration:
velocity: 
Explanation:
The complete question is written bellow:
<em>A cat is moving at 18 m/s when it accelerates at </em><em> for 2 seconds. What is his new velocity? </em>
<em />
In this situation the following equation will be useful:
Where:
is the cat’s final velocity (new velocity)
is the cat’s initial velocity
is the cat's acceleration
is the time
Solving the equation:
This is the cat's new velocity
Well I can't see the following physical properties you talked about in the question.
Mass per unit volume ratio is called density.
