Write the given then substitute it. Multiply the value of velocity to itself and multiply by given mass and divide it by 2 to get the value of Kinetic Energy.
What is the Kinetic Energy of a 1200 kg object that is moving with a speed of 24 m/s?
Fruit hangs from a tree. The fruit is a quarter of a kilogram and is about to fall to the ground. If the fruit is 10 meters from the ground, how much potential energy does it possess?
Write the given and remember the constant value of acceleration (9.8m/s2). Substitute the given and multiply it to get the value of Potential Energy.
Given: KE = ? m = 1200kg v = 24m/sKE = ½ mv2KE = ½ (1200kg) (24 m/s)2KE = ½ (1200kg)(576))KE = 345,600 J
