Kinetic energy i’m not 100% but like 85% sure
<span>A. kinetic energy. </span>
Friction converts kinetic energy into heat, and so it represents a net loss of mechanical energy. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. As demonstrated by the use of friction created by rubbing pieces of wood together to start a fire, kinetic energy is converted to heat whenever motion with friction occurs. The friction produced by brake pads in a car must generate a quantity of heat equal to the kinetic energy of the car and as a result, the brakes get quite hot.
Gravitational force or gravitational pull involves the attraction between objects with mass
Ashley ran with a speed of 12 feet per second.
Speed is measured as the ratio of the distance travelled to the time it took to cover that distance.
Since speed simply has a magnitude and no direction, it is a scalar quantity.
The formula for the speed of an object/body is given as-
where, d is the distance travelled by the body/object and t is the time taken by the body/object to cover the distance
Ashley has covered a distance of 264 feet and the time taken to cover this distance is 22 seconds.
Now, Ashley’s speed can be calculated by dividing the distance of 264 feet to the time taken by Ashley cover this distance, i.e.
Thus, the speed with which Ashley ran was 12 feet per second.
