Answer:
The height from which the egg is dropped is <u>68.54 m</u>.
Explanation:
Given:
Initial velocity of egg is, (Dropped means initial velocity is 0)
Time taken is,
Acceleration experienced by egg is due to gravity,
The height from which the egg is dropped is,
Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.
So, we have the following equation of motion:
Plug in all the given values and solve for 'd'. This gives,
Therefore, the height from which the egg is dropped is 68.54 m.
Answer:
Explanation:
The fish falls from vertical rest in a time of
t = √(2h/g) = √(2(2.27)/9.81) = 0.68 s
v = d/t = 5.6 / 0.68 = 8.2 m/s
Answer:
5.25MJ
Explanation:
Considering the weight of the skydiver constant over the descent -ie, the acceleration of gravity not decreasing as you go up the earth surfice, the work is simply the product of the two:
Answer:
