The above velocity / time graph shows a runner travelling at a constant speed, and then slowing to a stop.Calculate the distance travelled by the runner in the 7 s shown.

Calculate the distance travelled by the runner in the 7 s shown.

For the velocity-time graph shown in figure below the distance covered by the body in last two seconds of its motion is what fraction of the total distance covered by it in seven seconds :-

9. A speedboat starts from rest and reaches a velocity of 20 m s-1 in 10 seconds. It continues at this velocity for a further 5 seconds. The speedboat then comes to a stop in the next 4 seconds. (i) Draw a velocity-time graph to show the variation of velocity of the boat during its journey. (ii) Use your graph to estimate the velocity of the speedboat after 6 seconds. (iii) Calculate the acceleration of the boat during the first 10 seconds. (iv) What was the distance travelled by the boat when it was moving at a constant velocity?

A marathon runner crosses the start line of a race at a speed of 1 m/s and accelerates at a constantrate of 2 m/s2 for 2 seconds.Which graph shows the relationship between displacement from the start line and time aftercrossing the start line?2/28/2023, 2:58:42 PM

The velocity graph of a car accelerating from rest to a speed of 90 km/h over a period of 30 seconds is shown. Estimate the distance traveled during this period. (Use M6 to get the most precise estimate. Round your answer to two decimal places.)
