Astronomy is the study of stars and planets.
Answer:
The earth moves two ways. It spins and it moves around the sun. The spinning of the earth is called rotation. It takes the earth about 24 hours, or one day, to make one complete rotation.
Explanation:
The Earth's Three Motions. The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as an unbalanced spinning top (equinoctial precession).
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.
ANSWER
EXPLANATION
To find the velocity of the bowling ball, we apply the law of conservation of momentum, which states that<em> the total momentum in a system is constant</em>.
Mathematically, it is written as:
where m = mass of bowling ball = 10.8 kg
M = mass of basketball = 0.58 kg
u = initial velocity of bowling ball = 12 m/s
U = initial velocity of basketball = -4 m/s
v = final velocity of bowling ball
V = final velocity of basketball = 9 m/s
Note: the initial velocity of the basketball is negative since it is moving in a different direction from the bowling ball.
We have to solve for final velocity, v.
Therefore, we have:
That is the final velocity of the bowling ball.
