after 30s, a runner is spriting at 3m/s. But, 10s later, the runner is sprinting at 3.8m/s. What is the runner's acceleration during this time?
i don't understand lmao
To determine the runner's acceleration, we need to use the formula:
acceleration = (final velocity - initial velocity) / time
Let's break down the information given:
Initial velocity (u) = 3 m/s
Final velocity (v) = 3.8 m/s
Time (t) = 10 s
Now, to find the runner's acceleration, we substitute these values into the formula:
acceleration = (3.8 m/s - 3 m/s) / 10 s
acceleration = 0.8 m/s / 10 s
acceleration = 0.08 m/s²
Therefore, the runner's acceleration during this time is 0.08 m/s².
