A 6.4 ton military fighter must land on a flight strip. If the plane lands at a speed of 368 mph, and the coefficient of kinetic friction is 0.72 between the wheels and the ground. If the runway must be at least 150% as long as the shortest possible landing distance of the fighter, what is the shortest distance that the runway can be constructed?
HELP PLEASE I HAVE NO IDEA!

Convert mph to m/s. It is about 165m/s
mg*mu*distance=1/2 vi^2 * m
Notice mass m divides out.
distance=1/2*1/mu*vi^2 
what is mu and vi? the last part 1/2*1/mu*vi^2
