A 6200kg African elephant charges at a speed of 10 m/s

What is the elephant kinetic energy

310000

Explanation:

mass (m) = 6,200kg

speed (v) = 10m/s

kinetic energy = 1/2 × mass × speed 2

KE = 1/2 × m × v2

KE = 1/2 × 6200× (10)2

KE = 3,100 × 100

KE = 310,000 S

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
