You are playing frisbee golf and get a hole in one by throwing the disc 75.6 m. if the disc traveled at a constant speed of 12.5 m/s. how long did it take to hit the target

6.05 seconds

Explanation:

we know that

The speed is the ratio between the distance and the time

Let

s -----> the speed in meters per second

d ----> the distance in meters

t ---> the time in seconds

In this problem we have

substitute in the formula and solve for t

Multiply by t both sides

Divide by 12.5 both sides

it is called kinetic energy

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
