(c) the driver of a car traveling at a speed of 17 m/s slams on the brakes and comes to a stop in 3 s. if we assume that the speed changed at a constant rate (constant net force), what was the average speed during this 3 s interval?


It may possibly be c i think |-/

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.


v_{avg}=8.5\ m/s



initial speed of the car, v₁ = 17 m/s

final speed of the car, v₂ = 0 m/s

car stops in time = 3 s

we need to calculate average speed

v_{avg}=\dfrac{v_1 + v_2}{2}

v_{avg}=\dfrac{17 + 0}{2}


v_{avg}=8.5\ m/s

average speed of the car during interval of 3 s is 8.5 m/s

Do you know the answer?
