Explanation:
Given that,
Weight = 280 lbs
Height = 60 ft
Power = 3.50 hp
(a). We need to calculate the work done by the boom on the fireman
Using formula of work done
Put the value into the formula
The work done by the boom is 21.59 Btu.
(b). We know that,
1 hp = 550 ft lbf
So, 
We need to calculate the time
Using formula of time
Put the value into the formula
The time is 8.7 sec.
Hence, This is the required solution.
The highest point of the wheel is the position of the wheel when its potential energy is greatest.
<h3>At what position of the wheel potential energy is greatest?</h3>
The position of the wheel when its potential energy is greatest when it is at the highest point because potential energy depends on the height of an object. If the object is at more height then it has more potential energy and vice versa.
So we can conclude that the highest point of the wheel is the position of the wheel when its potential energy is greatest.

Heya!!
For calculate aceleration, lets applicate second law of Newton:
<u>Δ Being Δ</u>
F = Force = 183 N
m = Mass = 367 kg
a = Aceleration = ?
⇒ Let's replace according the formula and clear "a":
⇒ Resolving
Result:
The aceleration is <u>0,49 meters per second squared (m/s²)</u>
Good Luck!!
