Question

please solve urgently required ​

Answer 1

Step-by-step explanation:

work done is equal to change in kinetic energy

initial energy = 0 m/s

final kinetic energy = 1/2*m*v^2

Also,

here m = 0.25 kg and

v= 10m/s

so kinetic energy= 1/2*0.25*10^2

=12.5 J

therefore work done ,W = 12.5-0= 12.5 Joules
