Question

A greyhound has a mass of 35 kg and can run at a speed of 20 m/s. What is the kinetic energy that a greyhound can achieve

Answer 1

Hi there!

Recall the equation for kinetic energy:

`\large\boxed{KE = (1)/(2)mv^2}`

KE = Kinetic energy (J)

m = mass (kg)

v = velocity (m/s)

Plug in the given values:

`KE = (1)/(2)(35)(20^2) = \boxed{7000 J}`
