Answer:
The runner's acceleration is 1.67 m/s².
Step-by-step explanation:
The runner's acceleration can be found using the equation, acceleration = change in velocity / time. In this case, the runner reaches a speed of 10 m/s after traveling for 6.0 seconds. To find the acceleration, we need to calculate the change in velocity. The initial velocity is 0 m/s, so the change in velocity is 10 m/s. The time is 6.0 seconds. Plugging these values into the acceleration equation, we get:
acceleration = (10 m/s - 0 m/s) / 6.0 s
acceleration = 10 m/s / 6.0 s
∴ acceleration = 1.67 m/s²
