Free-falling body: h = -15t + 1/2at^2 + 5 (Solve for a)

1 answer:

7 0

When a body is said to be in a state of free fall, therefore this means that the only force associated with it is gravity. Gravity imposes an acceleration of about 9.81 m/s^2. Therefore we do not need to calculate for a, since a = g. (g = acceleration due to gravity)

insens350 [35]

The original price would be 190 because if you add 5 to 90 you get 95. 95 is half of the original price so you multiple 95 times 2 to get the original price.

____INVERSE PROPORTION_____

Shtirlitz [24]

Answer:

d ≈ 5.66

Step-by-step explanation:

given that F varies inversely with d squared, then the equation connecting them is

F = $\frac{k}{d^{2} }$ ← k is the constant of variation

to find k use the condition when F = 8, d = 6

k = Fd² = 8 × 36 = 288, hence

F = $\frac{288}{d^{2} }$

when F = 9, then

9 = $\frac{288}{d^{2} }$ ← multiply both sides by d²

9d² = 288 ( divide both sides by 9 )

d² = 32 ( take the square root of both sides )

d = ± $\sqrt{32}$ , hence

d ≈ 5.66 ← positive value only
