Question

question 2 (3 points) (02 02 mc) the table below shows data of sprints of animals that traveled 75 meters. at each distance marker, the animals times were recorded. which animal moves with non - accelerated motion? time at distance markers animal 1 animal 2 animal 3 animal 4 25 meters 13 seconds 14.5 seconds 13.5 seconds 13 seconds 50 meters 25 seconds 24.5 seconds 17 seconds 10 seconds 75 meters 35 seconds 25 seconds 10.5 seconds 13 seconds a animal 1 b animal 2 c animal 3 d animal 4

Explanation:

Step1: Recall speed formula

Speed $v=\frac{d}{t}$, where $d$ is distance and $t$ is time. We want to find the animal that reaches 75 meters in the least time as it has the highest non - accelerated speed for this part of the motion.

Step2: Check times for 75 - meter mark

For Animal 1: Time at 75 meters is 5 seconds.
For Animal 2: Time at 75 meters is 5.25 seconds.
For Animal 3: Time at 75 meters is 10.5 seconds.
For Animal 4: Time at 75 meters is 13 seconds.

Step3: Compare times

We see that Animal 1 has the least time (5 seconds) to reach 75 meters.

Answer:

a. Animal 1
