Answer:

Explanation:
Given the initial velocity of the clown, his mass and final height we can calculate the final kinetic energy using the <em><u>conservation of total mechanical energy</u></em>



Since 



Answer:
along the lead, at right angles to the lead at the middle, and at right angles to the lead at one end.
The area nearest to the earth's core is the densest..
So your answer would be letter choice ( D ) . . .
Hope it Helped :)
For this case we have that according to Newton's second law it is true that:

Where:
F: It is the force
m: It is the mass
a: It is the acceleration
According to the data we have:

So, we have:

Thus, the applied force will be 7 Newtons.
