O O 2. The height aftert seconds of an object projected upward with an initial velocity of 48 feet per second from a 210-foot tower can be
modeled by h = - 16t? + 48t + 210. The height of a neighboring 50-foot tall building is modeled by the equation h = 50 . The time (t) when
the object will be at the same height as the building is found to be t = -2 and t = 5. Which statement BEST describes the validity of
these solutions?
The solution t = - 2 is the only solution since 5 seconds is an unreasonable amount of time for the object to reach a height of 50 feet.
O Neither solution is valid since time values cannot be squared.
Both are valid solutions to this system since both values make the equation h = - 16t? + 48t + 210 true.
O The solution t = 5 is the only valid solution to this system since time cannot be negative.
