Question

The Potential energy of a body of mass 50 kg is 4900 J calculate it's height from the ground g = 9.8 m/s² ​

Answer 1

Answer:

h = 10m

Explanation :

Potential energy = mgh

given, potential energy = 4900J. m = 50kg. g = 9.8m/s

substitute the values and you will get :

4900 = 50 × 9.8 × h

4900 = 490 × h

h = 10m

Answer 2

Potential energy is the energy possess by the body due to virtue of its motion.

Step 1.

PE.=mgh

4900=50×9.8×h

Step 2.

4900=490 ×h

h =10 m

Final answer is h =10 m.
