a 2kg bowling ball rolls at a speed of 10 m/s on the ground

circle one: ke, gpe or both

show work finding the values of each rype of energy the object has..

100 J of kinetic energy but no gravitational potential energy if GPE of the ground is assumed to be zero.

Kinetic Energy

The ball carries kinetic energy for being in motion. The size of that energy is given as:

where

SI units:

For this ball:

.

Gravitational Potential Energy

Whether the ball carries gravitational potential energy depends on the point of zero potential energy. The ball would carry GPE if the point of zero potential energy is chosen underground. However, the question emphasizes that the ball is "on the ground," which implies that the ground is the reference with a GPE of zero.

The gravitational field near the Earth's surface is constant. As a result, GPE is proportional to height relative to the ground (or the point of zero GPE). The ball is on the ground. Its height is zero. As a result, its GPE is also zero.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
