11/16 Calculate Acceleration (2) ways POSSIBLE POINTS: 11.1 Joe started to drive faster when the police turned on the siren. Joe's initial velocity was 10m/s He accelerated to 20m/s in 4 seconds. Determine Joe's acceleration. square m/s/s

To calculate Joe's acceleration, we can use the formula:<br /><br />Acceleration = (Final Velocity - Initial Velocity) / Time<br /><br />Given information:<br />- Initial velocity (v1) = 10 m/s<br />- Final velocity (v2) = 20 m/s<br />- Time (t) = 4 seconds<br /><br />Substituting the values in the formula:<br /><br />Acceleration = (v2 - v1) / t<br />Acceleration = (20 m/s - 10 m/s) / 4 s<br />Acceleration = 10 m/s / 4 s<br />Acceleration = 2.5 m/s²<br /><br />Therefore, Joe's acceleration is 2.5 m/s².
