Cheryl runs a race 400.0 m circular track. she starts running east of the starting line and then circles the track and falls, stopping 1.00 m west of the starting line. her time is 80.0 s. what was her average velocity?

0.0125 m/s west

Explanation:

The velocity of an object is defined as the rate of change of the position of the object per unit time. In formulas:

where

d is the displacement (which is the diffence between the final and starting position of the object)

t is the time

In this problem, the displacement is just d=1.00 m (west), because this is just the difference between the final position (1.00 m west of the starting line) and the starting point). The time taken is t=80.0 s, so the average velocity is

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

50 inches should be the resultant vector
