Step-by-step explanation:
Given : A 2-kg bowling ball rolls at a speed of 5 m/s on the roof of the building that is 40 tall.
To find : Is it KE or GPE or Both
Solution :
Mass of the ball - 2 kg
Velocity of the ball - 5 m/s
Height - 40 tall
Both the energy is applied on the object.
1) Kinetic energy (KE)
Formula to find KE is 


Kinetic energy is 25 joule.
2) Potential energy (GPE)
Formula to find GPE is 
g is the acceleration due to gravity, 


Potential energy is 784.8 joule.

Answer:
912.
Step-by-step explanation:
- The centimeter is defined as a unit of lenght. Its symbol is: "cm".
- 1 centimeter=10 milimeters.
- The milimeter is defined as a unit of lenght and its symbol is "mm".
1. If you want to convert 47 milimeters to centimeters by using proportions, you have:
10 mm/1 cm=47mm/x
2. Then, you only have to clear the "x":
(10 mm)x=(47mm)(1 cm)
x=(47 mm)(1 cm)/10 mm
3. Therefore, the result is:
x=4.7 centimeters
Answer:
See below
Step-by-step explanation:
13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}
14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)
