Aforce of 100 n acts uphill on a 4 kg mass which sits on a surface with μ = 0.7 inclined at 23 degrees. find the acceleration.

as per FBD we can see that there are two forces opposite to our applied force F

1. Component of weight along the inclined plane

2. Friction force along the inclined plane

now in order to find the acceleration we will use Newton's II law

here we can say that net force is given by

now we can find friction force by its formula

here normal force is

now we have

now net force is given by

now acceleration is given by

now we will plug in all values in above expression

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
