" An object moves along the x-axis with initial position x(0) = 2

The velocity of the object at time t>/= 0 is given by v(t) = sin(pi/3t)

A: for 3< t < 4.5 the velocity of the object is decreasing

B: for 3< t < 4.5 the speed of the object is increasing

Are either both of these statements correct? For each statement provide a reason why it is correct or not.

What is the position of the object at time t=4? "

help please, thanks
