The "speed" of an alpha particle will be determined by what it is that generates that alpha particle. That's another way of saying that alpha particles, which are helium-4 nuclei, come in different energies. You will recall that they are generated in alpha decay, which is a form of radioactive decay. As to how "fast" they are in water, all we can state is an initial energy, and then do some calculations to determine how far they might go. As a sheet of notebook paper will stop an alpha particle, it will not travel very far in water. Small fractions of an inch is all we could expect for the distance they'd be able to go. Heck, they'd be bumping into water molecules right from the gate, and losing energy with each collision (which is called a scattering event). Links to related questions can be found below.
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
Plutonium is especially an alpha particles emitter.
The factors that will affect the extent of scattering of alpha particles include the charge and mass of the nucleus they interact with, the impact parameter (closest approach distance), and the energy of the alpha particles. Additionally, the angle of deflection will be influenced by the velocity and direction of the alpha particles as they approach the nucleus.
Alpha particles can be absorbed by water.

A fast-moving helium nucleus is also known as an alpha particle. It consists of two protons and two neutrons bound together. Alpha particles are commonly produced in nuclear reactions and are highly ionizing.

Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
some of alpha particles were deflected through an angle of 90 degree
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.

The symbol of the alpha particle is the small Greek letter alpha, α
Alpha particles are the strongest of the three known types of radiation (alpha, beta, & gamma). Although the strongest, the alpha particles are the least penetrating.They do not tend to penetrate any substance.A well-known example is your skin. Alpha particles do not penetrate your skin barrier. However, alpha particles energy is high and is a cause of skin cancer and genetic mutations.
No. You can produce alpha particles in a number of ways, but that's not really "cloning" as the term is usually used, even if all alpha particles are indistinguishable from each other.
