Answer:
20 Joules
Explanation:
Mechanical Energy is the sum of kinetic and potential energy.
Since energy can only be transferred and cannot be lost, kinetic energy=potential energy.
Now we only need to use one of the formulas to find the answer. In this answer I'll be using the formula for potential energy which is mass × gravitational field strength ×height.
Substitute the values in and using gfs=10, the answer will be 20J.
