Answer:

7.0 m/s

Step-by-step explanation:

We can solve this using the 2 kinematic equations and you can use either:

$Vf=Vi+at\\\\vf^{2}=vi^{2}+2ad$

So let's use the first one.

Vi = initial velocity

Vf = final velocity

a = acceleration due to gravity (constant 9.8m/s²)

t = time

The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.

We are given then the following:

d = 2.5m

t = 0.71s

Vi = 0 m/s

a = 9.8m/s²

So we plug in the values we know and solve:

$Vf = Vi + at\\\\Vf = 0 m/s + (9.8m/s^{2})(0.71s)\\Vf = 6.958m/s \cong 7.0m/s$

A town has a population of 14000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole n

Lyrx [107]

This is exponential growth. Use the formula P = 14000 (1+0.025)^5.

Note that (1+0.025)^5 = 1.025^5 = 1.131. Mult. the given population, 14000, by this factor to find the answer. Then round off your answer to the nearest whole number.
