After 30 s, a runner is sprinting at 3 m/s. But 10 s later, the runner is sprinting at 3.8 m/s. What is the runner’s acceleration during this time?
Wow mister Damon ur really smart. i dont know anything abot this 😅😅
Hey Aaron i need the awnser duh
To find the runner's acceleration during this time interval, we can use the formula for acceleration:
Acceleration (a) = (Final Velocity - Initial Velocity) / Time
First, let's calculate the initial velocity. We know that after 30 seconds, the runner is sprinting at 3 m/s. Therefore, the initial velocity (u) is 3 m/s.
Now, let's calculate the final velocity. We are given that 10 seconds later, the runner is sprinting at 3.8 m/s. Therefore, the final velocity (v) is 3.8 m/s.
Finally, let's calculate the acceleration:
Acceleration (a) = (3.8 m/s - 3 m/s) / 10 s
Simplifying this equation, we get:
Acceleration (a) = 0.8 m/s / 10 s
Acceleration (a) = 0.08 m/s²
So, the runner's acceleration during this time is 0.08 m/s².
(3.8 - 3) / 10
look at the question below this one.
