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


How much time does the car take to stop?
Answer in units of s

Answer 1

convert 94 km/hour to m/s then use
\[V _{f}^{2} = V _{o}^{2} +2ad\]

Answer 2

Have any questions about that?

Answer 3

sorry about that

Answer 4

okay 96 converted is 26.11 then v^2=26.11^2+2ad

Answer 5

yo somebody help
