Acar started to move ftom the rest and covers 2 km distance producing an acceleration of 0.5m/s2 find its velocity how long time does it take to cover the distance of 1.6km

(a) 44.7 m/s

We can find the final velocity of the car by using the SUVAT equation:

where

v is the final velocity

u = 0 is the initial velocity (the car starts from rest)

is the acceleration

is the displacement

Solving for v,

(b) 80 s

We can find the time it takes for the car to cover 1.6 km by using the following SUVAT equation:

where in this case we have

d = 1.6 km = 1600 m is the displacement

is the acceleration

u = 0

t is the time

Solving for t, we find:

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
