0.6468 this is the answer to your work you Welcome
Explanation:
energy cannot be created or destroyed, but only changed from one form to another or transferred from one object to another.
Answer:
Explanation:
i )
In a conservative field like gravitational field , loss of potential energy or work done , depends upon the initial and final point and not the manner in which 2 nd point has been reached . Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .
Hence , due to increased mass of larger child , his kinetic energy will be greater .
ii ) Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .
iii ) Smaller child undergo free fall , therefore , he will fall with acceleration g . The larger child falls on curved path . So , he will have only a component of
vertical g at any moment . hence average acceleration will be less.
The car would take 20 seconds to go 1000 meters. This can be found by dividing 1000 by 50.
