An object is launched at a velocity of 10 m/s with an angle elevation of 45°. a) Find the initial vertical velocity. (trig)
b) What is the maximum height reached by the object? (Use an equation in Desmos)
c) Find the initial horizontal velocity. (trig)
d) How far does the object go from the launch point? (Use an equation in Desmos)
e) What is the total flight time (between launch and hitting the ground) of the object?

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
