A feather is dropped on the
moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67
m/s2. Determine the time for the feather to fall to the surface
of the moon.
An engineer is designing the
runway for an airport. Of the planes that will use the airport, the lowest
acceleration rate is likely to be 3 m/s2. The takeoff speed for this
plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum
allowed length for the runway?
Answer: t = 1.29 s
Answer: d = 704 m
