Question

a block is suspended 5 m above the ground if the block has a mass of 20 kg how much potential energy is stored in the block (g= 9.8 PE= m*g*h

Answer 1

Answer:

P.E = 980 Joules

Explanation:

Given the following data;

Mass = 20 kg

Height = 5m

Acceleration due to gravity = 9.8 m/s²

To find the potential energy stored in the block;

Mathematically, potential energy is given by the formula;

$P.E = mgh$

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the equation, we have;

$P.E = 20 * 9.8 * 5$

P.E = 980 Joules
