Question

A dog of mass 16 kg is running at a constant speed of 12 m/s.calcukate the kinetic energy of the dog

Answer 1

Answer:

1152 J

Explanation:

As per the provided information in the given question, we have :

• Mass of dog = 16 kg
• Speed of dog = 12 m/s

We are asked to calculate the kinetic energy of the dog.

As we know that,

⇒ K.E = ½mv²

• K.E denotes kinetic energy
• m denotes mass
• v denotes velocity/speed

Substituting values in the formula.

⇒ K.E = ½ × 16 × (12)²

⇒ K.E = 8 × 144

⇒ K.E = 1152 J

∴ Kinetic energy of the dog is 1152 J.
