The motion of a particle is defined by the equations and x = (2t + t^2)m and y=(t^2)m, where t is in seconds.
A) Determine the normal component of the particle's velocity when t= 2s .
B) Determine the tangential component of the particle's velocity when t=2s.
C) Determine the normal component of the particle's acceleration when t=2s.
D) Determine the tangential component of the particle's acceleration when t=2s.
