What is the kinetic energy of a 2000 kg boat moving at 5 metre per second?

25000 J  or  25 k J

Explanation:

KE=1/2 mv²

kinetic energy = 1/2 *mass* velocity ²

where mass is in kilograms  k g

and velocity is in metres per second  m / s .

here, m=2000

v=5

v²=25

1/2mv² = 1/2 · 2000 · 25

=50000/2

=25000

KE = 25000 J  or  25 k J

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

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
