Question

A cheetah can run briefly with a speed of 31.0 m/s. Suppose a cheetah with a mass of 47.0 kg runs at this speed. What is the cheetah’s kinetic energy? Show your work please!(5 pts)

Answer 1

The cheetah’s kinetic energy is 22583.5 J

Step-by-step explanation:

Kinetic energy is defined as the energy that causes a body in motion. And its formula is as follows:

Ek = mv^2/2

where m = mass = 47 kg

v = velocity = 31 m/s

replacing values, we will have:

Ek = (47x(31)^2)/2 = 22583.5 kg*m^2/s^2 = 22583.5 Joule

Answer 2

Answer:22583.5J

Explanation: M=47.0 kg

V= 31.0 m/s

K.E =?

K.E = 1/2MV2

K.E = 1/2 X 47 X (31)^2

K.E = 1/2 X 47 X 961

K.E = 22583.5J
