If you accelerate due to gravity (free fall), your acceleration is -9.8 m/s2. In some fields, particularly aviation, this is referred to as 1 g of acceleration.

Question

If you accelerate due to gravity (free fall), your acceleration is -9.8 m/s2.  In some fields, particularly aviation, this is referred to as 1 g of acceleration. 
If you were accelerating at 2.5 g, what would be your average acceleration? 
If you started from rest, what would be your speed after 10 s?
What would be your average speed during the acceleration?
How far would you have travelled in this time?

Q1.a = 2.5 * -9.8 = -24.5m/s^2. Q2. V = Vo + g*t = 0 + 9.8*10 = 98 m/s. Q3. V = 0.5g*t = 4.9*10 = 49 m/s. Q4. d = 0.5g*t^2 = 4.9*10^2 = 490 m.
