Identify the unknown nuclide or particle (X).

$$X \rightarrow_{28}^{65} \mathrm{Ni}+\gamma$$

Explain how a particle can be accelerating even though its speed is constant.

Figure 2-17 gives the velocity of a particle moving on an $x$ axis. Is it constant or varying?

Make a graph of the kinetic energy versus momentum for a particle of nonzero rest mass

Why don't we notice energy quantization or particle wavelengths in everyday objects?

How can the momentum of a particle increase by $5 \%$ with only a $1 \%$ increase in speed?

Sketch the graph of the height of a particle against time if velocity is positive and acceleration is negative.

If the kinetic energy of a particle is doubled, by what factor has its speed increased?

Sketch the graph of the height of a particle against time if velocity is positive and acceleration is negative.

If the kinetic energy of a particle is tripled, by what factor has its speed increased?

Describe the structure of a typical atom. Identify where each subatomic particle is located.

Is an electron a wave or a particle? Support your answer by citing some experimental results.

The speed of a particle at t = a is given by the value of the velocity at t = a. Justify your answer.

Show that if the speed of a particle along a curve is constant, then the velocity and acceleration vectors are orthogonal.
