Question

Due this Friday, Jan 25 at 11:59 pm (EST) A car travels a certain distance along a straight road and on the way must stop at traffic lights and obey the local speed lmits. The distance the car travels as a function of time is shown in the figure below. Choose all the correct answers which apply to the speed of the car 1.5 1.25 8 0.75 d 0.5 0.25 0 Tim (min) Correct: The speed at 2.2 min is greater than at 6.0 min. Correct: The speed is zero at 0.6 min and 4.3 min. Incorrect: The speed doesnt change from 3 to 4.3 min Correct: At 2.2 min, the speed is as high as it gets Incorrect: The speed at 2.5 min is greater than at 22 mn ou are correct
uie auooe, and bloose ALL the correct answers which apply to the acceleration of the car ncorect The acceleration is zero at 0.6 min and 2.9 min. ncorrect The acceleration is never negative Correct The acceleration is not zero at 3.3 min. Correct The acceleration is not zero at 6.0 min. Correct The acceleration is not zero at 2.2 min. Acceration is the rate of change of velocity (acceleration n (change in velocity)/tme). If the velocity changed there must have been an acceleration. Submit Answer tit You have entered that anawer before Incorrect. Trhes a/10 Prevyious Tries

Answer #1

correct since the slope is constant at 0.6 min and 2.9 min . hence the acceleration is zero.

incorrect at points where the slope becomes zero from a positive value, the acceleration is negative.

correct

incorrect at 6 min , the slope is constant , hence constant speed so no acceleration.

incorrect
