Question

An object of mass 15kg is moving with a uniform velocity of 4m/s kinetic energy possessed by the

object is __________J.​

Answer 1

Given:-

• Mass of Object = 15kg

• Initial Velocity = 4m/s

To Find:-

• The Kinetic energy of the object

Formulae used:-

• K. E = ½ × m × v²

Where,

• K. E = Kinetic Energy
• m = Mass
• v = Final Velocity

Now,

→ K. E = ½ × m × v²

→ K. E = ½ × 15 × (4)²

→ K. E = ½ × 15 × 16

→ K. E = 15 × 8

→ K. E = 120J

Hence, The Kinetic Energy of the object is 120J.

Answer 2

Answer:

See explanation

Explanation:

mass is 15 kg

velocity is 4m/s

KE = 1/2mv^2

putting values we get

= 1/2 × 15 × 4^2

8 × 15

=130Joules
