Kinetic Energy Problem
"A moving object generally said to have kinetic energy."
Kinetic Energy Definition
Kinetic energy is one of many types of energy that exist. This is energy generated because something is moving — the faster it's going, the more kinetic energy it has. A person sitting has no kinetic energy, but a person running like a maniac has tremendous kinetic energy:
- The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed.
Kinetic Energy Definition (Cont)
The amount of kinetic energy KE of an object in translational motion is equal to one-half the product of its mass m and the square of its velocity v.
Kinetic energy is given as follows,Kinetic energy = ½(mv2)
A herder is herding his sheep into the kraal. A mother sheep and its lamb are both running at 2,7 m·s−1 towards the kraal. The sheep has a mass of 80 kg and the lamb has a mass of 25 kg. Calculate the kinetic energy for each of the sheep and the lamb
- Velocity or speed of mother sheep and lamp, v =2.7 m·s−1
- Mass of the mother sheep = 80 kg
- Mass of the lamb = 25 kg
- Kinetic energy of mother sheep
- Kinetic energy of lamb
