Answer:
h=20.66m
Explanation:
First we need the speed when the cord starts stretching:
This will be our initial speed for a balance of energy.
By conservation of energy:
Where
is your height at its maximum elongation
is the height of the bridge
is the length of the unstretched bungee cord
Solving for h:
and Since 99m is higher than the initial height of 79m, we discard that value.
So, the final height above water is 20.66m
Answer:
0.7 m.
Explanation:
We are given that
Initial velocity of fox,v=12 m/s
Distance of fox from the ball=3.2 m
Horizontal component of velocity=
Vertical component of velocity=
Time taken by fox to travel in horizontal direction=
Time taken by box to the wall=0.28 s
Formula:
Where
Using the formula
Takine g negative because fox going against to gravity.
Hence, the fox will reach upto height 0.7 m when it reaches the wall
Answer:
The correct option is b) By the time they get to be theories, they cannot be disproven. It's not necessary that the theories are always right. They can be proven wrong.
