Posición, velocidad, aceleración

A particle moves along a curve whose parametric equations are x = 3t2 , y = 4 sen3t , z = 5 cos2t. Find its velocity and acceleration. Find the magnitudes of the velocity and acceleration at t = 0.

S O L U C I Ó N:

(A)

x = 3t2

vx = 6t

ax = 6

y = 4 sen3t

vy = 12 cos3t

ay = -36 sen3t

z = 5 cos2t

vz = -10 sen2t

az = -20 cos2t
