Consider a rabbit that is at x=8.1 m a t=0 and moves with a constant velocity of -1.6 m/s. what is the equation of motion for the rabbit?

Since the rabbit is moving at constant velocity, therefore the acceleration is zero, hence the increase in distance over time would simply be:

x = v t

where v is velocity and t is time, x is distance

Since we are starting at x = 8.1 m, the equation of motion would therefore be:

x = 8.1 – 1.6 t

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

the answer would be c
