Answer:
<h2>500 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have
We have the final answer as
<h3>500 J </h3>
Hope this helps you

Answer:
Explanation:
It may not make any difference. The information missing is the radius of the planet.
However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..
The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase. The question is done by a proportion.
