Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
![K.E=\frac{1}{2} mv^{2} \\](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B1%7D%7B2%7D%20mv%5E%7B2%7D%20%5C%5C)
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}](https://tex.z-dn.net/?f=2%20K.E%20%3D%20mv%5E%7B2%7D%5C%5C%5C%5Cv%5E%7B2%7D%20%3D%20%5Cfrac%7B2%20K.E%7D%7Bm%7D)
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](https://tex.z-dn.net/?f=v%5E%7B2%7D%3D%5Cfrac%7B2%20%5Ctimes%2032%7D%7B36%7D%5C%5C%5C%5C%20v%5E%7B2%7D%3D%5Cfrac%7B16%7D%7B9%7D%5C%5C%5C%5C%20v%3D%5Cfrac%7B4%7D%7B3%7D%5C%5C%5C%5C%20%20v%3D1.33)
Thus, the object is moving with a velocity of 1.33 m/s
Answer:
The earth moves two ways. It spins and it moves around the sun. The spinning of the earth is called rotation. It takes the earth abut 24 hours, or one day, to make one complete rotation.
