A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has energy. Calculate it.

8.9*10^5

Explanation:

as we know that  

K.E =1/2 mv²

where m is mass and v is velocity

given mass= 1120 kg

given velocity =40 m/s

so K.E=1/2 (1120)(40)²

K.E=1792000/2

K.E=896000

K.E=8.9*10^5

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

it is called kinetic energy
