What initial speed does the proton need

Reference no: EM13534317

A proton is fired from far away toward the nucleus of an iron atom. Iron is element no. 26 (i.e., Q=26 x 1.6 E -19 C). What initial speed does the proton need so that its turning point is 9 E -15 m from the nucleus? Assume that the nucleus remains at rest.
