Answer:
Step-by-step explanation:
Given that the position vector of a moving body at time t is

Velocity is the derivative of acceleration
v(t) =
, t positive
Speed would be the magnitude of the velocity and will not have direction
Speed = 
Acceleration of the object
a(t) = derivative of velocity of vector
= 
i.e. acceleration would be in the direction of x axis alone.
