Answer 2

Here, as per the provided question we are asked to find the kinetic energy of the object -

GIVEN :

• Mass of a body = 10kg
• Uniform speed of a body = 5m/s (per)

TO FIND :

• Kinetic Energy of a body = ?

STEP-BY-STEP INSTRUCTIONS :

Now, we are said to find the kinetic energy taken by the body = ?

→ Kinetic Energy = ½mv²

[ substituting the values<]

→ Kinetic energy = ½ × 10×5^2

→ Kinetic energy = ½ × 10×25

→ Kinetic energy = 250/2 = 125 (Reduced)

→ KINETIC ENERGY = 125JOULE

Therefore, kinetic energy of the body is 125 joule (j) (b)125j✓.
