Show that the average speed of a rabbit that runs a distance
of 30 m in a time of 2 s is 15 m/s.
I have a whole bunch of problems such as these and i'm not sure what math formula to use to figure problem.I know its Acceleration !
change of velocity
time interval
!
"v
"t
but how do I work it out
average speed = distance / time
= 30 m / 2 s
= 15 m/s
acceleration is another matter entirely
It is CHANGE in velocity / time
To find the average speed of the rabbit, you need to divide the total distance traveled by the time taken.
In this case, the distance traveled by the rabbit is 30 m, and the time taken is 2 s.
The formula for average speed is:
Average Speed = Total Distance / Total Time
Plugging in the given values, we have:
Average Speed = 30 m / 2 s
To simplify this, divide the distance by the time:
Average Speed = 15 m/s
Therefore, the average speed of the rabbit is 15 m/s.
Please note that in this problem, we are calculating average speed, not acceleration. Average speed is the total distance traveled divided by the time taken, while acceleration is the change in velocity divided by the time taken.
