D. Speed and direction, this is because velocity is a vector quantity so has a magnitude and direction assigned to it because it is the rate of change of displacement.

It takes significantly stronger magnetic and electric field strengths to move a beam of alpha particles compared with the beam of electrons(betaparticles) because the charge of an alpha particle is twice stronger than a beta particle. Therefore, more energy is needed to move the alpha particle.
Answer:
A Thermal energy was converted to kinetic energy
Answer:
The acceleration of the object is -69.78 m/s²
Explanation:
Given;
postion of the particle:
The velocity of the particle is calculated as the change in the position of the particle with time;
Acceleration is the change in velocity with time;
