Question

if the car from problem #1 takes a longer time to travel the 60 meters, how does that affect its speed? increase decrease stays the same you run a lap (400 m) around a track in 80 seconds and end up in the same place your started. what is your velocity? velocity = displacement/time 0 m/s 5 m/s 32 m/s 50 m/s

Explanation:

Step1: Recall speed formula

Speed = distance/time. Distance is fixed at 60 meters. If time increases, according to the formula, speed will decrease.

Step2: Recall velocity concept

Velocity = displacement/time. Since you end up at the same place you started, displacement is 0 meters. Time is 80 seconds. So velocity = 0/80 = 0 m/s.

Answer:

1. B. decrease
2. A. 0 m/s
