Answer:
2.45 m
Explanation:
We are given that
Height,h=0.75 m
Initial velocity,
We have to find the height above his own starting point Ed rises.
Initial kinetic energy of Ed=Final potential energy of Ed
According to law of conservation of momentum
Initial kinetic energy of adolf=Final potential energy of adolf
Substitute the values
I would let someone more confident in this field to answer this question but that sounds like a Chemical reaction
<u><em>Correct question:</em></u><u><em>a </em></u><u><em>200 g </em></u><u><em>ball is dropped from a height of 2m, bounces on a hard floor and rebounds to a height of 1.5m. What maximum force does the floor exert on the ball?</em></u>
<u><em>The diagram of the question is in the attachment.</em></u>
Answer:
Explanation:
V=√2gh
g-10m/s²
let u be initial velocity ad v be final velocity,
u=√2*10*2
u=6.324m/s
v=√2*10*1.5
v=5.477m/s
from the diagram
t=5ms=0.005s
F=-33.87N (the negative shows direction)
From the diagram Fmax=2F
Fmax= 2*33.87
=67.74N
Answer:
10V = 1mA(1Ω + Rs)
Rs=10-1
Rs=9Ω
