Question

Calculate the kinetic energy of a 4.00kg object traveling at 16.0 m/s

Answer 1

KE = ½mv² = ½(4.00 kg)(16.0 m/s)² = 512 J

Answer 2

Kinetic energy is 512 Joules

Step-by-step explanation:

Given that,

Mass of the object, m = 4 kg

Velocity with which the object is moving, v = 16 m/s

We need to find the kinetic energy of the object. It is given by :

`E_k=(1)/(2)mv^2`

`E_k=(1)/(2)* 4\ kg* (16\ m/s)^2`

`E_k=512\ J`

So, the kinetic energy of the object is 512 Joules. Hence, this is the required solution.
