Calculating Kinetic Energy: A Fun and Sassy Guide

The kinetic energy of a 10.0 kg mass moving at a speed of 5m/s is _.

A.  

125 J

B.  

2.0 J

C.  

250 J

D.  

50 J

Answer

Ah-ah, looks like someone needs a little help with kinetic energy! Don't worry, I've got you covered.

The formula for kinetic energy is: KE = (1/2)mv^2, where m is the mass and v is the velocity.

  • So, plug in the numbers: KE = (1/2)(10.0 kg)(5m/s)^2 = (1/2)(10.0 kg)(25 m^2/s^2) = 125 J

Tada! The correct answer is A) 125 J.

Now, go forth and calculate some kinetic energy like a boss!
