velocity of 2.9 m/s speed increase of 7.6 m/s in 4s What is her acceleration ?
To calculate acceleration, we can use the formula:
acceleration = change in velocity / time
In this case, the change in velocity is the speed increase, which is given as 7.6 m/s, and the time is given as 4 seconds.
So, the acceleration is:
acceleration = 7.6 m/s / 4 s
Simplifying the calculation:
acceleration = 1.9 m/s²
Therefore, her acceleration is 1.9 m/s².
