The momentum of the truck is given by:
p = mv
p = momentum, m = mass, v = velocity
There isn't too much work to do here; the truck is at rest, therefore its velocity is 0. This means the product of m and v is 0, giving the momentum as 0.
Question: What happens to potential energy when a skier goes down the hill?
Answer: Decrease
Explanation: As the skier begins the descent down the hill potential energy is lost and kinetic energy is going to start acting

distance d = 5 km = 5 x 1000 m = 5000 m
time taken = 25 minute = 25 x 60 sec = 1500 sec
average velocity V = d/t
V = 5000/1500
V = 3.33 m/s towards east
There are 5 carbon atoms present in the Chemical formula,
.
<h3>What is a chemical formula?</h3>
A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.
From the chemical formula;
We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;
Carbon = 1 atom
Hydrogen = 1 atom
Chlorine = 3 atoms
So, in 5 molecules of the compound;
Carbon = 1 x 5 = 5 atoms
Hydrogen = 1 x 5 = atoms
Chlorine = 3 x 5 atoms = 15 atoms
In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of
