Using the Pythagorean theorem we can find the distance from the swimming pool to the courthouse:
Swimming pool to courthouse:
Distance = √(3^2 + 4^2)
Distance = √(9+16)
Distance = √25
Distance = 5 kilometers
Now total the distance the bird flew:
Courthouse to Library is given as 3 kilometers.
Library to swimming pool is given as 4 kilometers
Swimming pool to courthouse we calculated as 5 kilometers.
Total distance = 3 + 4 + 5 = 12 kilometers.
To solve this problem, we will need the standard kinematics equation
where
v0=initial velocity (positive upwards) m/s
t=time in seconds
a=acceleration due to gravity (positive upwards) = -9.81 m/ ²
Substituting values,
distance = 0 (when it falls back on earth)
v0=42 m/s
a=-9.81 (negative means towards earth, downwards)
factor and solve
=>
t=0 (beginning of launch), or
42-(1/2)*9.81t=0 => t=2*42/9.81=8.563 s.
Time to return = 8.6 seconds (to the nearest tenth of a second)
3 : 3 times 6 is 18, 2 times 9 is 18 and 3 times 3 is 9 plus 9 is 18
