a falling object travels a distance given by the formula d=5t + 16t^2 ft, where t is measured in seconds. how long will it take
Butoxors [25]

Its given that

d=5t+16t^{2}

We need to find t when d = 74

Therefore, 74=5t+16t^{2} or

16t^{2}+5t-74 = 0

16t^{2}+37t-32t-74 = 0

t(16t + 37) - 2(16t + 37) = 0

(t - 2)(16t + 37) = 0

t - 2 = 0 or 16t + 37 = 0

t couldn't be negative.

Therefore, t = 2

Hence, it will take 2 seconds for the object to travel 74 feet.
