For an object in circular motion, the centripetal force is given by:
where
m is the mass of the object
v is the tangential speed of the object
r is the radius of the circular path
Therefore, we see from the formula that there are three physical quantities that affect the value of the centripetal force: the mass of the object, its speed and the radius of its orbit.
Answer:
-25 m/s
Explanation:
Since the ball was caught at the same height, it has the same speed and opposite direction that it went up with.
Answer: the basic unit of a chemical element.
Explanation:
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
