Question

A 10 kg object is moving at a speed of 5m/s. The kinetic energy of the object will be

Answer 1

GIVEN : Mass of object ,m = 10 kg

Speed of object,v = 5m/s

TO FIND : "kinetic energy of object"

SOLUTION :

as we know ,

kinetic energy = 1/2mv^2

= 1/2 × 10 × 5^2

= 5×5×5

= 125 joules or J

ANSWER :

─━━━━━━⊱✿⊰━━━━━━─

The mass of the object, m = 10 kg

The speed of the object, v = 5m/s

The Kinetic Energy, K.E = ?

We know that ,

$kinetic \: energy = \frac{1}{2} mv ^{2}$

From this ,,,

Kinetic Energy ,K.E = 1/2 × 10 × (5)^2

K.E = 5 × 25

K.E = 125 J

The Kinetic Energy is 125 J.
