How do you calculate mass with distance of 30m and kinetic energy 4392j

Use the formula,  to answer. We need the Mass, which is weight divided by acceleration. So, let's solve for F (force):


Plug in known values:


Solve:


Then, since we need mass, assuming we are on Earth, and there are no neutron stars, or anything like that close by, we can divide the weight by acceleration of gravity (9.8 m/s^2) to get the mass:


Simplify:

Gravity bc it’s gravity
