To solve this problem we will apply Newton's second law. The second law says that mass by acceleration is equivalent to the Force exerted on a body. Mathematically this
Here,
m = mass
a = Acceleration
The ball flies through the air under the effect of gravity only. Therefore the acceleration is due to gravity, we have that
Then,
Replacing
The negative sign implies that the force acting on the ball is in the downward direction that is towards the negative y direction.
Temperature: Kelvin or degree Celsius; thermometer
Length: meter and its fractions and multiples; ruler
Volume: liter or cubic meter, mm, cm, km etc.; ruler for regular solids or empty spaces, graduated cylinder or kitchen measuring cup for liquids and irregular solids
Mass: kilogram and its multiples and fractions; balance with calibrated samples, or scale with knowledge of local gravity, or methods of applying known force and measuring acceleration
I'm sorry, but this is not a question. What do you need to know?
