Hi Friend
______________
Kinetic energy= 1/2mv^2
here m= 10 kg
velocity=4m/s
so kinetic energy = 1/2X10X4X4
=80 joules

Mistake in K.E, 1/2(mv²), v²=16, not 6 plzz correct it
Not 4 i mean

Kinetic energy-energy pocessed by a body with respect to its velocity.
It is given by:
K.E=1/2 (mv²) (formula)
[Where, m=mass , v=velocity]
Since we have been given the values:
m=10kg
v=4 m/s
K.E=1/2(10×4²) [applying the above formula]
=1/2(10×16)
=1/2(160)
=80J (unit of energy Joule)
