The mass of an object with 500 j of kinetic energy moving with a velocity of 5 m/s is
kg. (report the answer to one significant figure.)

Mass of an object, m = 40 kg

Explanation:

It is given that,

Kinetic energy of an object, KE = 500 J

The object is moving with velocity of 5 m/s. We have to find the mass of an object. Kinetic energy is possessed due to moving body. Mathematically, it can be written as :

m = 40 kg

So, the mass of an object is 40 kg. Hence, this is the required solution.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

it's a b and
