Answer:
The maximum height is 10 meter.
Step-by-step explanation:
Given : A body of mass 1 kg projected vertically up with certain velocity. At certain point it's potential energy and kinetic energy are 8 J and 90 J.
To find : The maximum height reached by it ?
Solution :
Mass of the body is 1 kg.
Potential energy is 8 J.
Kinetic energy is 90 J.
Gravitational force g=9.8 m/s².
Mechanical energy is defined as the sum of kinetic and potential energy in an object that is used to do work.
So,
Now, At highest point Kinetic energy became zero.
Therefore, The maximum height is 10 meter.
