Calculate the acceleration if you ride your bike down hill and the initial velocity is 2 km/hr and the final velocity is 23 km/hr and it takes you .25 hours to go down the hill

We can calculate the acceleration by using a kinematic equation that relates what is given to us with respect to acceleration. In the problem, we are given:

Vi = 2 km/hr

Vf = 23 km/hr

t = 0.25 hours

The kinematic equation that relates these values is:

Vf = Vi + at

Plugging in these values, we find that:

23 = 2 + a(0.25)

a = 84 km/hr^2

The acceleration of your bike is 84 km/hr^2.

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
