Question

find the kinetic energy of a body of mass 4 kg moving with velocity 6 m/s​

Answer 1

Hey there

MARK AS BRAINLIST

If the answer helps you

Let's start

QUESTION - Find the kinetic energy of a body of mass 4 kg moving with velocity 6 m/s

Answer -

NOTE - UNITS PLAY A MAJOR ROLE

As you might be knowing

KINETIC ENERGY = 1/2( MASS* VELOCITY *VELOCITY)

NOW HERE ITS GIVEN

MASS=4 KG

VELOCITY = 6 M/S

PUT THE VALUES IN FORMULA

KINETIC ENERGY = 1/2( 4 *6*6)

ON SOLVING

KINETIC ENERGY = 1/2(144)

THEN

KINETIC ENERGY =72 JOULES

HOPE IT HELPED YOU

Answer 2

Answer:

kinetic energy

$\frac{1}{2}mv {}^{2}$

mass= 4 kg

velocity= 6 m/s

$\frac{1}{2} \times 4 \times 6 \times 6 \\ = > 72joule$
