A car travelling at 35 m/s has a
kinetic energy
of 500,000 J.
what is the
mass?

I NEED HELP FIGURING THIS OUT

816.33 kg

Explanation:

To solve this problem we'll need to keep in mind the formula for the kinetic energy of an object:

Where E is the kinetic energy, m is the object's mass and v its velocity.

We input the data given by the problem:

And solve for m:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
