Question

A driver in a car traveling at a speed of
56.6 mi/h sees a deer 106 m away on the
road.
Calculate the magnitude of the acceleration
necessary for the car to stop just barely missing
the deer (assuming that the deer does not
move in the meantime).
Answer in units of m/s

Answer 1

change speed to m/s

then
Vf^2=Vi^2+2ad solve for a. d=106
