Question

A test of the prototype of a new automobile
shows that the minimum distance for a controlled stop from 94 km/h to zero is 41 m.
Find the acceleration, assuming it to be
constant as a fraction of the free-fall acceleration. The acceleration due to gravity is
9.81 m/s
2
.
Answer in units of g

Answer 2

\[\Delta v^2=2a \Delta x\]
Will find the acceleration.
\[\Delta v = a \Delta t\]
will find the time.
