Answer:- The Kinetic energy of the car is 12000 J.

Explanation:

Kinetic energy is the energy posessed by an object by virtue of its motion.

K.E=\frac{1mv^2}{2}

m= mass of object = 1500 kg

v= velocity of object = 4 m/s

Putting in the values in the equation:

K.E=\frac{1500kg\times 4^2ms^{-1}}{2}

K.E=12000kgm^2s^{-2}=12000N      1kgm^2s^{-2}=1J

Thus Kinetic energy of the car is 12000 J.

Which two atoms could be the "before'' and ''after'' of an alpha ejection
spin [16.1K]
The answer would be uranium and thorium. When an alpha ejects a particle, it will create a new atom. So, when uranium ejects an alpha particle, it will produce thorium.  They call this process as the alpha decay. Alpha decay often happens on atoms that are abundant nuclei such as uranium, radium, and thorium.
