Question

A rider is training a horse. Horse moves 60 metres towards right in 3 seconds. Then it turns back and travels 30 metres in 2 seconds. Find its average velocity and show your working?

A. 6 m/s
B. 18 m/s
C. 35 m/s
D. Zero​

Answer 1

The answer is A which is 6m/s

Step-by-step explanation:

Avg. Velocity = Total Displacement/total time

displacement = 30 metres

time= 5 seconds

then Avg. Velocity= 30/5=6m/s

your answer will be 6m/s

Answer 2

We can use the formula for average velocity, which is:

average velocity = total displacement / total time

The total displacement is the net distance and direction of the horse's motion. If we take "towards right" as the positive direction, then the horse's displacement is:

total displacement = 60 m towards right - 30 m towards left = 30 m towards right

The total time is the sum of the two time intervals:

total time = 3 s + 2 s = 5 s

Now we can plug in the values and calculate:

average velocity = total displacement / total time

average velocity = 30 m / 5 s

average velocity = 6 m/s

Therefore, the answer is A. 6 m/s.
