Answer:
511.1 J
Explanation:
We are given that
Mass of wood block=m=3 kg
Vertical distance,h=23 m
Horizontal distance =x=30 m
Distance traveled in downward direction y=40 m
Initial velocity,u=0
Where
By work energy theorem
Change in kinetic energy=Work done= mgh-W
Hence, the work done due to friction on the block as it slides down the ramp=511.1 J
