A test of the prototype of a new automobile
shows that the minimum distance for a con-
trolled stop from 100 km/h to zero is 41 m.
Find the acceleration, assuming it to be
constant as a fraction of the free-fall accel-
eration. The acceleration due to gravity is
Answer in units of g.
The Attempt at a Solution
I'm actually unsure how to even begin this problem. The statement has me confused, such as what they mean by "a fraction of the free-fall acceleration."
