Answer:
F = 160 pounds
B. 160 pounds
Step-by-step explanation:
F = k / l
Where,
F = amount of force needed
l = length of the lever
k = constant of proportionality
F = 240 when l = 24 inch
F = k / l
240 = k / 24
Cross product
240*24 = k
k = 5,760
Find F when l = 36 inch
Recall, k = 5,760
F = k / l
= 5,760 / 36
= 160
F = 160 pounds
The correct answer is B. 160 pounds
Answer:
Step-by-step explanation:
h(x) = 36 - 4.9x^3
Let x be 1.3
The question is not entirely clear. Looks like the iphone moved. Not only that, but the question is not really clear either. I'm taking it to mean that h is the distance from the GROUND to the ROCK after 1.3 seconds.
h(x) = 36 - 4.9(1.3)^2
h(1.3) = 36 - 4.9 * 1.3 * 1.3
h(1.3) = 36 - 27.719
h(1.3) = 8.28 m
