J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
Explanation:We have momemtum = mass X velocity
p = mv
OR, p/m = v
v = (125kg m/s)25kg
v = 125/25 m/s
v = 5 m/s
