Answer:
200.
Step-by-step explanation:
0-49=round down 50-99=round up.
You can write the equations of motion as
h(t) = -16t² + v₀sin(θ)t
d(t) = v₀cos(θ)t
Solving the second of these for t and substituting into the first equation gives the time of flight as
0 = -16t² + d(t)·tan(θ)
t = √(d(t)·tan(θ)/16)
So, for d(t) = 400 and θ = π/6, this becomes
t = √((400/16)/√3)
t = 5/√(√3) ≈ 3.79918
The ball is in the air about 3.80 seconds.
45 will most likely be the least affected because it is the median of the data set, everything else would have been brought down or up by a gradual amount but since 45 is the middle number, it most likely won't.
