We assume
(acceleration is constant. We apply the equation
where s is the distance to stop
. We find the acceleration from this equation
We know the acceleration, thus we find the distance necesssary to stop when initial speed is
Answer:
Approximately 66,8kg
Hope this help :D
Explanation:
F=mg. So 655N= 9.8 m/s² × mass.
Mass = 655 / 9.8
<span>The atomic number of
a neutral atom is equal to the number of protons and the number of electrons of
the atom. The atomic weight meanwhile is equal to the sum of the number of
protons and number of neutrons. In this case, the number of protons is equal to 26. The number of neutrons hence is 30. </span>
<u>Answer</u> :
atom
<u>E</u><u>xplaination</u> :
You cannot see the fundamental particles that makes up matter.
