Kenny and Chris are walking down the road. They walk a distance of 250meters in
2 answers:
Answer:
Explanation:
Speed is the rate an object moves. It is found by dividing the distance by the time.
Kenny and Chris walked a distance of 250 meters in 50 seconds. So:
- d= 250 m
- t= 50 s
Substitute the values into the formula.
Divide.
Kenny and Chris had an average speed of <u>5 meters per second.</u>

1) Displacement: -49 m, in the negative direction
Explanation:
The displacement of an object is a vector, whose magnitude is given by the difference between the final point of the motion and the starting point:
In this problem, the starting point is +34 m, while the final position is -15 m; therefore, the displacement is:
and the direction is negative, in according to the negative sign.
2) Velocity: -3.27 m/s
Explanation:
Velocity is equal to the ratio between the displacement and the time taken:
in this problem, we have:
d = -49 m is the displacement
t = 15 s is the time
therefore, the velocity is
and the direction is negative.
