A lizard accelerates from 2m/s to 10m/s in 4 seconds. What is the lizards average acceleration?
a=changevelocity/time=8/4 m/s^2
To find the average acceleration of the lizard, we can use the formula for average acceleration:
Average acceleration = change in velocity / change in time
Given that the lizard accelerates from 2 m/s to 10 m/s in 4 seconds, the change in velocity is:
Change in velocity = final velocity - initial velocity
= 10 m/s - 2 m/s
= 8 m/s
The change in time is given as 4 seconds.
Now we can plug these values into the formula for average acceleration:
Average acceleration = change in velocity / change in time
= 8 m/s / 4 s
= 2 m/s²
Therefore, the average acceleration of the lizard is 2 m/s².
