Question

A ball of mass 0.8 kg is dragged in the upward direction on an inclined plane. Calculate the total potential energy gained by this ball given that the height of the wedge is 0.2 meter. (g = 10 m/ s²) please do it mannerly.

Answer 1

Answer:

1.6 J

Explanation:

Formula for potential energy = mass * gravity* height

= 0.8* 10* 0.2

= 1.6 J

Hope it helps. Pls mark as branliest

Answer 2

Answer:

The total potential energy gained by the ball is 1.6J.

Explanation:

Given the mass of a ball,  m = 0.8 kg

Height of the wedge, h = 0.2 m

And acceleration due to gravity, $g = 10 m/ s^{2}$

Potential energy is defined as the energy possessed by a body by virtue of its position.

If a body of mass m is raised to certain height h, then the work done in raising against the force due to gravity will be stored as potential energy at the position.

Hence, the potential energy is given by

$PE=mgh$

$=0.8\times 10\times 0.2=1.6J$

Therefore, the total potential energy gained by the ball is 1.6J.
