400 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 kg

Height (h) = 8 m

Workdone (Wd) =?

Workdone by gravitational force is given by the following equation:

Wd = mgh

Where:

Wd => is the Workdone.

m => is the mass of object

g => is the acceleration due to gravity

h => is the height to which the object is located.

With the above formula, we can obtain the workdone as follow:

Mass (m) = 5 kg

Height (h) = 8 m

Acceleration due to gravity (g) = 10 m/s²

Workdone (Wd) =?

Wd = mgh

Wd = 5 × 10 × 8

Wd = 400 J

Thus, the workdone by gravitational force is 400 J

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
