See the step by step solution

Step by Step Solution

Part (a) step 1: Given information

We need to determine the speed of a neutron.

Part (a) step 2: Simplify

Energy of motion is

Part (b) step 1: Given information

We need to determine the speed of a helium atom.

Part (b) step 2: Simplify

Energy=,

Mass=

Velocity is

part (c) Given information

We need to determine the specific type of particle that has of kinetic energy when moving with a speed of .

Part (c) step 2: Simplify

Energy=

Velocity =

Since the mass of the particle is equal to electron, hence the unknown particle is electron.
