Here,
height at failure, h1 = 525 m,
upward acceleration, a = 2.25 m/s^2,
velocity = v m/s,
<span>
SO, </span>
<span>
v^2 = 2*a*h = 2*2.25*525 = 2362.5 </span>
Now, acceleration, g = 9.8 m/s^2,
<span>
SO, </span>
<span>
heigt, h1 = v^2/2g = 2362.5 / 2*9.8 = 120.54 meters </span>
Hence,
<span>
a) </span>
Total height = 525+120.54 = 645.54 meters
b)
<span>time, for h1, t = v/g = sqrt(2362.5)/9.8 = 4.96 sec

Answer:
6.41 s
Explanation:
Under constant acceleration we know that
average velocity × time taken = displacement
t = 6.41 s
The proof of used equation is given in the attachment.
Answer:
21,000 N
Explanation:
You would use the formula F=ma
So you would do substitution...
F=700 kg(30 m/s/s)
F=21,000 N
V=IR
= 2 x 6
= 12V
Resistors in series add together:
(2ohms x 2) + (1ohms x 2)
4 + 2 = 6 ohms
Hope this helps!
It is the force applied to a machine
in order to accomplish work.
