Kinetic energy is 25 joule
Potential energy is 784.8 joule
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.
let's solve :
- 2 [30 - (1 + 4)²]
- 2 [30 - (5)²]
- 2 [30 - 25]
- 2 [5]
- 10
