An object has a kinetic energy of 32 J and a mass of 36 kg, how fast is the object moving?

marin [14]

Answer:

1.33 m/s

Explanation:

The formula for Kinetic Energy is given as:

$K.E=\frac{1}{2} mv^{2} \\$

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.

Re-arranging the above equation and isolating v, we get

$2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}$

Putting values in this equation, we get:

$v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\ v=1.33$

Thus, the object is moving with a velocity of 1.33 m/s
