How much force would it take to throw a 0.5 kg basketball at an acceleration of 20 m/s??

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

From the question

mass = 0.5 kg

acceleration = 20 m/s²

We have

Force = 0.5 × 20

We have the final answer as

Hope this helps you

Explanation:

Force can be found by multiplying the mass by the acceleration.

The mass of the basketball is 0.5 kilograms.

The acceleration is 20 meters per second squared.

Substitute the values into the formula.

Multiply.

A kilogram meter per second squared is equal to a Newton.

Therefore, 10 kilogram meters per second squared is equal to 10 Newtons.

10 Newtons of force would be required.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
