Answer:
His acceleration is meters per seconds²
Step-by-step explanation:
Acceleration is the rate of change of the speed
The formula of acceleration is , where
is the final speed
is the initial speed
- The unit of the acceleration is meters/second²
∵ Jim goes from 70 meters/minute (beginning speed) to
106 meters/minute (final speed) in 9 seconds
∴ His initial speed = 70 meters/minute
- Change it the meter per second
∵ 1 minute = 60 seconds
∴ meters/second
∴ =
meters/second
∵ His final speed = 106 meters/minute
- Change it the meter per second
∴ meters/second
∴ =
meters/second
∵ The time of the change of his speed is 9 seconds
∴ t = 9
∵ The formula of acceleration is
- Substitute the values of t, and
in the formula above
∴
∴ His acceleration is meters per seconds²
