Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².
<h3>What is the velocity formula?</h3>
It is given by the initial velocity plus acceleration multiplied by time, that is:
v(t) = v0 + at.
In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:
v(t) = v0 + at.
19.6 = 0 + 2a.
2a = 19.6.
a = 19.6/2.
a = 9.8 m/s².
The acceleration is of a = 9.8 m/s².

Answer:
Marcus position: -18 meters
Step-by-step explanation:
We establish a reference system where the zero height is on the sea surface. Then all height below the sea surface is negative.

⊥ Marcus: - 18 meters
So the position of marcus is: -18 meters above sea level.
To return to the surface you must move 18 meters up.
Answer:
201.1 meters squared
Step-by-step explanation:
A= pi*r squared
Diameter= 16, to find the radius we must divide by 2
16/2=8
Radius= 8
A= pi* (8)^2
A= 201.06
The area of the circle is 201.1 meters squared.
Answer:
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19
