Question

an object of mass 15kg is moving with a uniform velocity of 4 m/sec .What is the kinetic energy possessed by the object.

Answer 1

Kinetic energy = 1/2*m*v^2
Mass=15kg
Velocity=4m/s
K.E= 1/2*15*4*4
Kinetic energy= 120 joules

Answer 2

Answer:

The kinetic energy possessed by the object is 120 J.

Explanation:

Given that,

Mass of the object m = 15 kg

Uniform velocity v = 4 m/s

We know that,

The kinetic energy is the defined as:

$K.E =\dfrac{1}{2}mv^2$

$K.E=\dfrac{1}{2}\times15\times4\times4$

$K.E= 120\ J$

Hence, The kinetic energy possessed by the object is 120 J.
