An atom of beryllium (m8.00 u) splits into two atoms of helium (m4.00 u) with the release of 92.2 kev of energy. if the original beryllium atom is at rest, find the kinetic energies and speeds of the two helium atoms. kinetic energy 6.1 speed kev x m/s

The kinetic energy and speed of the two helium atoms are and .

Explanation:

Given that,

Mass of beryllium = 8.00 u

Mass of helium = 4.00 u

Energy = 92.2 keV

We need to calculate the kinetic energy

The kinetic energy of the helium atom is the half of the total kinetic energy released.

Therefore, the kinetic energy of the each helium atom is

We need to calculate the speed

Using formula of speed

Hence, The kinetic energy and speed of the two helium atoms are and .

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
