Question

An object of mass 15 kg is moving with a uniform velocity of 4m per second what is the kinetic energy possessed by the object.

Answer 1

Answer:

120joule

Explanation:

K.E =1/2*m*v^2 =1/2*15*4*4 =120joule

Answer 2

Here :

Mass , m = 15 kg

Velocity , v = 4m/s

To Find :

The kinetic Energy possessed by this object.

Formulae to be used :

Kinetic Energy = ½ mv²

= ½ ×15 × 4² = 120 Joules.

The required kinetic energy possessed by the object is 120 J.
