2. You are designing an airport for small planes and one kind of airplane that must use this airfield should reach a minimum speed of at least 100km/hr before takeoff and can accelerate
at least 2m/s?
a) If the runway length is 150m long, can this airplane reach the minimum speed before
takeoff?
b) If otherwise, determine the length that the runway should have for this plane to reach the
minimum required speed before takeoff.

An object thrown vertically upward from the surface of a celestial body at a velocity of 36 m/s reaches a height of sequalsminus0.9tsquaredplus36t meters in t seconds. a. determine the velocity v of the object after t seconds. b. when does the object reach its highest point? c. what is the height of the object at the highest point? d. when does the object strike the ground? e. with what velocity does the object strike the ground? f. on what intervals is the speed increasing?
