Question

Calculate the kinetic energy of an object weighing 600kg moving at a velocity of 30m/s

Answer 1

Answer:

Kinetic energy =1/2*mass*velocity sq.J

=1/2*600*30*30 joule

(2 and 600 will be simplified and we get 300)

=300*30*30Joule

=270000 joule

Answer 2

Answer:

W=600g

V=30m/s

=1/2×600×30×30

=2÷600×30×30

=300×30×30

= 27000
