8. The position of a particle moving in a circular path is given by r(t) =< -4 sin(3t), 4 cos(3t) >. Find the speed v of the particle at any time t.
Can some one help me with this please, I think I got it right
but would like to make sure.

A particle moves along a circular path of radius 10 ft. If its position is 8 = 0.74 - 1 rad, where t, is in seconds, determine the magnitude of the particle's acceleration when 8 = 0.53 radians. Note that the magnitude is a scalar, if you were asked for acceleration you would need to give a vector Give answer to at least 3 decimal places jäl =
