This position time graph describes an objects motion. Use it to determine the displacement ( in m ) of the object after 6.0 seconds of motion. Enter the appropriate + or - sign.

Can I get some help with part (c) and part (d) in justifying whether or not a line fits the data on the Position Time Graph. For part (c) the scale should be in meters. Thank you very much.

While standing on a bridge 13.9 m above the ground, you drop a stone from rest. When the stone has fallen 3.30 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction. Number i Units

Problem 12 Some troublemaking kids are dropping water balloons from the roof of your apartment building. You are in your fifth-floor room and your window is 25 m above the sidewalk outside. You look outside and see that each balloon hits the pavement 1.5 s after passing your window. Express answers using 2 significant figures. a) How fast are the balloons traveling when they pass your window? b) Assuming the balloons are being released from rest, from what height above your window are they being released? c) If you threw a balloon upwards from your window with an initial speed of 6.5 m/s, would you be able to get it to the roof?

What is the average speed of the walker for this distance in km/h? km/h 5. DETAILS A tortoise and a hare cover the same distance in a race. The hare goes very fast for brief intervals, but stops frequently, whereas the t hare. (a) Which of the two racers has the greater average speed over the duration of the race? OThe tortoise has the greater average speed since he was the winner. The hare has the greater average speed since he can go faster. Their average speeds are equal. OIt's impossible to determine who had the greater average speed without collecting data. (b) Which of the two racers is likely to reach the greatest instantaneous speed during the race? OThe tortoise has the greater instantaneous speed since he was the winner. OThe hare has the greater instantaneous speed since he can go faster.
