(i)What was the average acceleration of the driver during the collision? Express the answer in terms of “g’s”.

(4 %)

(ii)How much energy was dissipated in the collision?

**drwls**, Tuesday, July 20, 2010 at 4:26pmi) Is 4% your guess at the answer?

If a is the deceleration rate,

Vinitial = sqrt(2 a X)

Solve for a. Convert Vinitial to m/s first.

ii) ALL of the initial kinetic energy was dissipated.
