1.03 x 10^6 J
It is a certain amount of energy, since a joule is a unit of energy.
245 calories.
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
Acceleration doesn't matter in either case.-- Potential energy of the lifted rock:PE = M G H = 5 x 9.8 x 5 = 245 joules-- Kinetic energy of the pushed rock:KE = 1/2 M V2 = (2.5) (12)2 = 360 joulesThe pushed rock requires more work ... 360 joules vs. 245 joules.
Shot putter transfers 245 J of energy to Kinetic energy of steel ball. Kinetic energy, T=(1/2)mv2 must keep track of units however. Joules=Kgm2/s2 So want mass in Kg 7200 g=7.2 Kg So we have: 245 Kgm2/s2=(1/2)*7.2 Kg*v2 v2=68.05 m2/s2 v=8.25 m/s
There are approximately 245 calories in a safeway apple fritter.
yeh more than 245
The formula for working out Potential enery is: PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons) - mass should be in Kg's - and height in meters - final answer should be in Joules (J) Therefore substitute it in :-) Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters) Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters
245 + 245 + 245 = 735
245 1*245 = 245 49*5 =245
245
