hello, I'm having trouble answering this question. Thanks for the help!

A car travels a certain distance along a straight road (in the +x direction), The distance the car travels as a function of time is shown in the figure below When the car changes speed it does so uniformly. Seect the appropriate choice for each statement 1000 E800 600 400 200 20 40 60 80 Time (s) True Less than Equal to Greater than Equal to Greater than At 50 sec, the speed is as high as it gets The acceleration magnitude at 15 sec is.. the acceleration magnitude at 38 sec. The speed is... zero at 23 sec. The speed at 4 sec is. the speed at 73 sec. The x-acceleration is zero at 64 sec. The x-acceleration is zero at 38 sec. jel yotr esuintate the sntrgilt de ctiothne arctelefrliph: you can estimate the time during which the speed is changing. This, with the change in speed, shouid let you estimate the magnitude of the acceleration. Submit Answer Incorrect. Tries 9/12 Previous Tries Using the qraph above, calculate the average speed of the car for the period from 0 to 80.0 s 9.90 m/s Submit Answer Incor Tries 2/12 Previous Tries

Explanation / Answer

True

equal to :since acceleration is 0 at both t = 15 sec and at t = 38 sec

equal to

greater than

equal to

greater than

True

average speed = total distance/total time = 1200 /80 = 15 m/s
