Question

If an object of mass 50 kg moves with a velocity of 20 m/s, calculate the
Energy possessed by the moving object.

Answer 1

Answer:

the positive of the moving object will be 30m/s

Answer 2

Given :

• Mass of the object, m = 50 kg
• Velocity of the object ,v = 20 m/s

Need to find :

• Energy possessed by the object ?

Solution :

As we know that,

⋆ KE = ½mv²

where,

• 'KE' denotes Kinetic Energy
• 'm' denotes mass
• 'v' denotes velocity

Putting the values,

➜ KE = ½ × 50 × 20²

➜ KE = ½ × 50 × 400

➜ KE = 25 × 400

➜ KE = 10,000 J

Hence, the Energy possessed by the object is 10,000 Joules.
