" 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
