Answer:

Step-by-step explanation:

Given that the position vector of a moving body at time t is

r(t) = (3t ^6,6t - 5,2 + 3t), t\geq 0

Velocity is the derivative of acceleration

v(t) = (18t^5, 6, 3), t positive

Speed would be the magnitude of the velocity and will not have direction

Speed = \sqrt{324t^{10}+36+9 } \\=\sqrt{324t^{10}+45)

Acceleration of the object

a(t) = derivative of velocity of vector

= (90t^4, 0,0)

i.e. acceleration would be in the direction of x axis alone.
