What is the kinetic energy of a 110 kg linebacker rushing towards his football
opponent? the linebacker is moving at a velocity of 5 m/s toward his target
work, and the answer with units:

The Kinetic energy of the 110 kg linebacker is 1375 J

Solution:

The kinetic energy of an object is the energy produced by its velocity. Kinetic energy of an object is directly proportional to the mass and the square of the its velocity.

Therefore, the formula for kinetic energy is

Here, The linebacker’s mass m = 110 kg

The linebacker’s velocity v = 5 m/s

So by substituting the values,

The kinetic energy of linebacker is

the answer is 1030 it's very simple math.
