Answer:
So the acceleration of the child will be
Explanation:
We have given angular speed of the child
Radius r = 4.65 m
Angular acceleration
We know that linear velocity is given by
We know that radial acceleration is given by
Tangential acceleration is given by
So total acceleration will be
Answer: 1. h
Explanation:
The block would reach exactly the same height from the ground. It would travel a greater distance away from the source, but the height away from the earth would remain the same as you are giving it the same energy each time. Therefore, it will reach the same gravitation potential energy.
Another approach to look at it this is seeing it when the Block moves up the slope, its kinetic energy decreases and the potential energy increases. In both cases, the kinetic energy decreases by same amount, therefore the block rises to same height H.
Try to use the formula;
1/2MV2 = mgh
Where V = √(2gh)
