1. T = V^2 / g
plug in given values for solutions to 2. and 3.
t varies directly as the square of v and inversely as the aquare root of g. T = 20 when V = 5 and g = 16. find:
1. the formular connecting T, V and g
2. T when V = 15 and g = 25
3. g when T = 40 and V = 10

UPDATE
1. T = k (V^2 / g) ... 20 = k (5^2 / √16) ... solve for k
plug in given values for solutions to 2. and 3.
1. T = k (V^2 / g) ... 20 = k (5^2 / √16) ... solve for k
plug in given values for solutions to 2. and 3.
"t varies directly as the square of v and inversely as the square root of g"
----> t = k (v^2/√g)
when T = 20 , V = 5 and g = 16
20 = k(25/4
k = 80/25
t = (80/25) v^2/√g
#2
find T when V = 15 and g = 25
t = (80/25)(225/5) = 144
#3. you try it
