Answer:
287J
Step-by-step explanation:
Given parameters:
Kinetic energy = 50J
Potential energy = 237J
Unknown:
Mechanical energy = ?
Solution:
The mechanical energy of a system is the sum of the potential energy and kinetic energy of that system.
Kinetic energy = Potential energy + Kinetic energy
Kinetic energy = 50J + 237J = 287J
