Question

An object has a kinetic energy of 35j and a mass of 24j kg,how fast is the object moving?

Answer 1

v = 1.7 m/s

Step-by-step explanation:

We have,

The kinetic energy of the object is 35 J

Mass of the object is 24 kg

It is required to find the speed of the object. If v is the velocity, then kinetic energy is given by :

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

or

`v=\sqrt{(2E)/(m)} \\\\v=\sqrt{(2* 35)/(24)} \\\\v=1.7\ m/s`

So, the speed of the object is 1.7 m/s.
