Question

If a 10-kilogram [kg] rotating solid cylinder moves at a velocity (v), it has a kinetic energy of 36 joules [J]. Determine the velocity the object is moving in units of meters per second [m/s] if the kinetic energy is given by KE=12/mv2+14/mv2.

Answer 1

v = 2.68 m/s

Step-by-step explanation:

Given that,

Mass of a solid cylinder, m = 10 kg

The kinetic energy of a solid cylinder, K = 36 J

We need to find the velocity of the object. The formula for the kinetic energy is given by :

`K=(1)/(2)mv^2\\\\v=\sqrt{(2K)/(m)} \\\\v=\sqrt{(2* 36)/(10)} \\\\v=2.68\ m/s`

So, the velocity of the object is 2.68 m/s.
