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?

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
