The graph shows the time versus distance data gathered for four different ball/marble rolls laboratory 02.
The first four questions are matching. Use the letters A, B, C, and D at the end of the lines on the xy scattergraph.
_____ Ball not moving: stationary.
_____ Ball slowing down.
_____ Ball moving at a constant non-zero speed.
_____ Ball speeding up.
___________________ Determine the speed of ball D.
___________________ Determine the speed of ball A.
___________________ Determine the speed of ball B between 4 and 5 seconds.
___________________ Determine the speed of ball C between 7 and 10 seconds.
___________________ The graph above was generated by a RipStik rider. The x-axis is time in seconds, the y-axis is the distance in meters. The equation of the line is y = 1.61x − 0.49. What is the speed of the RipStik?
___________________ On Saturday 15 January I ran from Dolihner, Nett to Kinakapw, Madolehnihmw, covering 19.8 kilometers in three hours. I consumed four bottles of water, a mini-can of Pringles, and a bag of karindo. What was my velocity ѵ in kilometers per hour?
_________________ Calculate your speed if you walk 36.8 meters in 18.4 seconds
_________________ At the walking speed calculated above, how long in seconds for you to walk the 1000 meters from the A101 classroom to Palikir Elementary School?
