Question 3

Answer 1

Answer:

G.P.E = 368.3

Explanation:

Given the following data;

Mass = 2.63kg

Height, h = 14.29m

We know that acceleration due to gravity is equal to 9.8m/s²

To find the gravitational potential energy;

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

$G.P.E = mgh$

Where;

G.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.

$G.P.E = 2.63*9.8*14.29$

G.P.E = 368.3

Note: the unit of gravitational potential energy is Joules.
