The figure below shows a position vs. time graph of a certain object. Which statements about the object's motion are true for the period of time shown in the graph?

The slope of an object's position-versus-time graph at time t is the object's. position at time t speed at time t average velocity between 0 and t velocity at time t acceleration at time t

The two lines on the position time graph describes the motion of two different objects. How much faster (in m) is the object moving compared to the slower object?

A particular rabbit accelerates from rest to a speed of 11.7 m/s in 1.2 seconds. What is the rabbit's average acceleration during that time interval? (Assume the acceleration is positive in our coordinate system, and give your answer in m/s2 .)

The table below shows data (position or velocity) for 8 different objects. Let west be the positive direction & east be the negative direction. Based on the data, determine whether each object SPED UP THE ENTIRE TIME, SLOWED DOWN THE ENTIRE TIME, or TRAVELED AT A CONSTANT VELOCITY. For each scenario (sped up, slowed down, & constant velocity) choose all that apply. Elapsed Time Velocity Velocity Velocity Velocity Velocity Velocity Velocity Velocity of object of object of object of object of object of object of object of object 1 2 3 4 6. 7 8 (s) (mm/s) (km/h) (m/s) (ft/min) (in/s) (mi/h) (in/min) (ft/s) -91 -81 -82 79 -88 84 17 72 1 -77 -84 69 -86 84 17 75 -91 2 -91 -73 -86 59 -84 84 17 78 3 -91 -69 -88 49 -82 84 17 81 4 -91 -65 -90 39 -80 84 17 84 Sped up Slowed down Constant velocity

The position vs. time graph for an object is shown here. What is this object's acceleration? (Note that when the graph is flat, the velocity is zero) 5- 2 2 time (s) position (m)

A ball decelerates in a straight path at 2.50 m/s2. Calculate the time it will take for the ball to completely stop with an initial velocity of 5 m/s. 3 s 2 s 5 s 4 s O 7s

A person gets in an elevator on the ground floor and rides it to the top of the building. Choose a velocity-versus time graph for this motion.

A runner maintains constant acceleration from rest, reaching 8.4 m/s after running 54 m. How much time did it take to reach that speed? t= S Record your numerical answer below, assuming three significant figures.
