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/s. the takeoff speed
for this plane will be 60 m/s. assuming this minimum acceleration, what is the
minimum allowed length for the runway?

Density of salty water as compared to the density of pure water is(a) is less(b) is always equal(c) is always more(d) may be less or more

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.
