Answer:

Both

Kinetic energy is 25 joule

Potential energy is 784.8 joule

Step-by-step explanation:

Given : A 2-kg bowling ball rolls at a speed of 5 m/s on the roof of the building that is 40 tall.

To find : Is it KE or GPE or Both

Solution :

Mass of the ball - 2  kg

Velocity of the ball - 5 m/s

Height - 40 tall

Both the energy is applied on the object.

1) Kinetic energy (KE)

Formula to find KE is KE=\frac{1}{2}mv^2

KE=\frac{1}{2}(2)(5)^2

KE=25

Kinetic energy is 25 joule.

2) Potential energy (GPE)

Formula to find GPE is PE=mgh

g is the acceleration due to gravity, g=9.81 m/s^2

PE=(2)(9.81)(40)

PE=784.8

Potential energy is 784.8 joule.
