Oliver hits a baseball at 3 feet above the ground with an initial speed of 135ft/sec at an angle of 20 degrees with the horizont

Serhud [2]

Answer:

Option B) the ball lands in front of the wall

Explanation:

1. Find the vertical and horizontal components of the initial velocity

a) Horizontal component:

$v_{0,x}=v_0\times cos(20\º)=135ft/s\times cos(20\º)=126.86ft/s$

b) Vertical component:

$v_{0,y}=v_0\times sin(20\º)=135ft/s\times sin(20\º)=46.17ft/s$

2. Find the time when the ball runs 380 feet horizontally:

$x=v_{0,x}\times t\\\\380ft=126.86ft/s\times t$

$t= (380ft)/(126.86ft/s)=2.995s\approx 3.0s$

3. Find the height of the ball when the time is 3.0s

$y=y_0+v_{0,y}\times t-gt^2/2$

y₀ = 3 ft
g ≈ 32.174 ft/s²

$y=3ft+46.17ft/s\times 3.0s-32.174ft/s^2\times (3.0s)^2/2$

$y=-3.3ft$

This result means that the ball does not reach the wall because it has fallen to the ground (when y = 0) before 3.0s.

David's cell phone company charges $0.45 for| each text message plus a monthly fee of $50.00. He owes $91.40. Write and solve an

Radda [10]

Let the number of text messages be represented by X.

Then the total cost of David's cell phone adds up to
$50.00 + 0.45x$

Since the total cost of David's phone equals $91.40, we get the following equation.
$50.00 + 0.45x = 91.40$

Subtract 50 on both sides
$0.45x = 41.40$

Divide both sides by 0.45
$x = 92$

Therefore David has send 92 text messages.
