Answer:
19.2
76.8
Step-by-step explanation:
density × volume = mass
mass = 62.4 × (pi × (40/2)² × h)
mass = 78,374.4h
WD = m×9.8×h = 9.8mh
WD = 768,069.12h²
At h = 5
WD = 768,069.12×5²
= 19,201,728 ft-lb
= 19.2 million ft-lb
At h = 10
WD = 76,806,9.12 × 10²
WD = 76,806,912 ft-lb
= 76.8 million ft-lb
To find how many miles he went in 1 hour, divide 62.3 by 3.5.
62.3 / 3.5 = 17.8
3 because 2*12 24 24/8 is 3 hope this helps
