O) A turtle starts at x = 2 and travels to the right to stand briefly at x = 5, and then travels to the left and comes to a stop at x = -1.  What is the turtle's change in position (displacement)?

S) Using s(t) as position and a(t) as acceleration, this integral is equal to

S) Using s(t) as position and a(t) as acceleration, this integral is equal to

B) A particle moves a long the  $$x-$$  axis. The function  $$x\left(t\right)$$  gives the particle's position at any time,  $$t\ge0$$  :  $$x\left(t\right)=5t^2-12t+3.$$  What is the particle's velocity  $$v\left(t\right)$$  at  $$t=3$$  seconds?

A) A particle moves a long the $$x-$$ axis. The function  $$x(t)$$ gives the particle's position at any time,  $$t≥0$$  :   $$x(t)=5t^2−12t+3.$$  What is the direction of the particle's motion at $$t=3$$  ?

B) A particle moves along the  $$x-$$  axis . The function  $$x(t)$$  gives the particle's position at any time  $$t≥0$$ ,  $$x(t)=2t^2-3t+5$$  . What is the particle's acceleration $$a(t)$$  at $$t=1$$  ?

Y) Which of the following is a unit for acceleration?

Use the graph above and pick the most accurate description of the object's motion

A particle moves in a straight line with a velocity of v(t) = 2t². How far does the particle move between times t = 1 and t = 3?

For times t > 0, a particle moves on the x axis with its acceleration defined by a(t) = 6t – 2. If the velocity of the particle is -7 at t = 1, then at what time is the particle at rest?

What does a flat (horizontal) line on a velocity-time graph mean?
