It will hit the floor when h=0

-16t^2+14.8t+3.9=0

using the quadratic formula...

t=(-14.8±√468.64)/-32, since t>0

t ≈ 1.139 seconds

There was a population of 240 moose in a National Park. After a year, the population increased by 25%.
Stels [109]
Population of moose in the national park = 240
percentage increase in the population of moose in the national park after a year = 25%
Then
Amount of increase in the population
Of moose in the national park in a year = (25/100) * 240
                                                               = 240/4
                                                               = 60
So
The number of moose present after 1 year
in the national park = 240 + 60
                                = 300
So from the above deduction we can easily conclude that the number of moose in the national park after a year is 300.
