Question

Calculate the kinetic energy of a 5.2 kg object moving at 2.4 m/s.​

Answer 1

Answer:

Kinetic energy, K = 14.97 J

Explanation:

We have,

Mass of the object, m = 5.2 kg

Velocity of the object, v = 2.4 m/s

It is required to find the kinetic energy of the object. As it is moving with some velocity, it will have kinetic energy. It is given by :

$K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 5.2\times (2.4)^2\\\\K=14.97\ J$

So, the kinetic energy of the object is 14.97 J.
