**Using the following formulas.**

Q = gm ± am [N]; Weight = gravity x mass + force x mass [Newtons]

F = a x m ; force = acceleration x mass [Newtons]

a = ΔV / t [m/s²]; acceleration = current velocity - start velocith divided by time

**Given:**

V = 100 km/h = 27.78 m/s //car speed

V(0) = 0 km/h = 0 m/s //car end speed

m = 70 kg //my mass in car

t = 1 s //crash speed, from top speed to car stopping

**To find out:**

Q = ?

**Calculations:**

Q = gm + am = 9.8 x 70 + 27.78 x 70 = 2630 kg = 2.6 tons (wow!)

a = ( 27,78 - 0 ) / 1 = 27.78 [m/s²]

Is this really so that my weight is 2.6 tons at the moment of crash?
