The amplitude is equivalent to the coefficient of the sine function, so:
Amplitude = 1
The time period of a Sin(x) = 2π
The time period of Sin(4x) = 2π/4 = π/2
The period is π/2
The ping pong ball was stopped because it lost its kinetic energy as it was made of plastic. The wooden ball gained the kinetic energy from the desk as it was also made out of wood.
That's my reasoning, Hope it is correct!
