The position of a particle at time t is given by(adsbygoogle = window.adsbygoogle || []).push({});

r(t)= i cos(t) + i sin(t) + kt

Show that both the speed and magnitude of the acceleration are constant. Describe the motion.

Answer:

Does constant mean they come out to b the same answer? For the speed will I take the derivative of r(t). Or is speed the same as magnitude? To get the magnitude I just the the sqrt of the equation with each element squared? What is the motion?
