What are the options young lad
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
The crate’s acceleration is gravity= 9.81m/s^2
The ball’s acceleration is also gravity=9.81m/s^2
A. fixed volume, changeable shape.
The acceleration will be doubled because the force and the acceleration are directly proportional please make my answer the brainliest. Thanks :)
