Question

A scientist wants to calculate the kinetic energy of a cheetah as it chases down its prey. What does the scientist need to measure in order to determine the kinetic energy of the cheetah?

Select all that apply.

the cheetah's amount of matter
the cheetah's speed
the amount of energy the cheetah absorbs from the sun
the amount of energy the cheetah releases into its surroundings
the cheetah's temperature

Answer 1

A + B

Step-by-step explanation:

A) The cheetah's amount of matter

B) The cheetah's speed

(P.S. I just took a test on this and got it correct.)

Answer 2

the cheetah's amount of matter

the cheetah's speed

Step-by-step explanation:

Kinetic energy is calculated according to the following equation

K.E =
`(mv^(2) )/(2)`

where m represents the mass of the body in kilograms

and v represents the magnitude of the velocity which is know as speed of the body in m/s

Knowing this then, the scientist needs two things from that list:

the cheetah's amount of matter (also known as the mass)

the cheetah's speed
