Answer:
Time elapsed
Explanation:
Acceleration is a vector quantity. It is defined as:
where
v is the final velocity
u is the initial velocity
t is the time elapsed
Acceleration is measured in meters per second squared (m/s^2). It must be noticed that acceleration is a vector, so it also has a direction. In particular:
- when acceleration is negative, it means that the object is slowing down, so acceleration is in opposite direction to the velocity
- when acceleration is positive, it means that the object is speeding up, so acceleration is in the same direction as the velocity
Remember what acceleration is? It's how fast the speed is changing over a period of time.
So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
Now that you know dv and dt, you can calculate the acceleration a!
So in dt = 2 secs, she sped up from 6 to 10 m/s and so dv = (10-6) m/s.
