an alpha particle from a certain radioactive source has a Kinetic energy of 8.2x10(-13)j. Using the information below, estimate how long it would ctake this particle to travel a distance equal to the diameter of the atom.(adsbygoogle = window.adsbygoogle || []).push({});

mass of alpha particle= 6.6x10-27kg

diameter of atom=1x10-10m

my answer

KE=1/2MV2

V2=(KEX2)/M

(9.2X10-13X2)/6.6X10-27= THE Square root of 2.48

which is obviously wrong, can u guyz help me adress the problem?
