In some rutherford scattering experiments, the alpha particles had kinetic energies of 9.3 mev . what’s the speed of such an alpha particle?

Speed of an alpha particle is,

Explanation:

It is given that,

Kinetic energy of the alpha particles,

Since,

Kinetic energy,

We need to find the speed of alpha particle. The kinetic energy os given by :

m is the mass of alpha particle,

v = 21113576.97 m/s

or

So, the speed of such an alpha particle is . Hence, this is the required solution.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
