The kinetic energy of an object is 550 J when it is moving at a velocity of 10 m/s. What is the object’s mass?

Sagot :

Paounn

Answer:

11 kg

Explanation:

Let's start by the definition of kinetic energy, that is [tex]K = {1\over2} m v^2[/tex], let's replace what we have and solve for what's left.

[tex]550 = {1\over2}\cdot m \cdot 10^2[/tex]

[tex]m = {550\cdot 2 \over 100} = 11 kg[/tex]
