The potential energy of a hammer of mass 10 kg, lifted to the height of 10 m is
100 J
10 J
98 J
980 J
Potential Energy = mgh = 10 kg x 9.8 ms-2 x 10 m = 980 J
What would be the gravitational potential energy of an object whose mass is 1kg and is at a height of 10m?(take g = 9.8 ms−2)
To what height should an object of mass 2kg be raised so that its potential energy is 980J?
Box of mass 10 kg is lifted through a height of 10 m in 49 seconds find the corresponding power
