Answer : Work done, W = 2560 J.
Explanation :
It is given that,
The mass of an object, m = 20 kg
Initial speed of the object, u = 0
Final speed of the object, v = 16 m/s
We know that the work done by an object is equivalent to the change in kinetic energy.
So, [tex]W=\dfrac{1}{2}m(v^2-u^2)[/tex]
[tex]W=\dfrac{1}{2}\times 20\ kg\times\ (16\ m/s-0)^2[/tex]
[tex]W=2560\ J[/tex]
So, the work done on this system is 2560 J.
