Answer:
The answer to your question is Ke = 2240 J
Explanation:
Data
mass of the object = 20 kg
mass of the girl = 50 kg
speed = 8 m/s
Kinetic energy = Ke = ?
Formula
Ke = 1/2 mv²
Process
Kinetic energy is due to the movement of an object.
1.- Calculate the total mass
Total mass = 20 + 50 = 70 kg
2.- Substitution
Ke = 1/2(70)(8)²
3.- Simplification
Ke = 1/2(4480)
4.- Result
Ke = 2240 J
Answer:
positive
Explanation:
