The Rogers Centre in Toronto, Ontario, has a center field fence that is feet high and feet from home plate. A ball is hit feet above the ground and leaves the bat at a speed of miles per hour. Determine analytically the minimum angle required for the hit to be a home run.

The question is not complete and the complete question is;

The Rogers Centre in Toronto, Ontario, has a center field fence that is 10 feet high and 400 feet from home plate. A ball is hit 3 feet above the ground and leaves the bat at a speed of 100 miles per hour. Determine analytically the minimum angle required for the hit to be a home run.

Angle = 19.4°

Step-by-step explanation:

In model for projectile motion, we know that;

→r(t) = (VoCos θ)tî + [h + (Vosinθ)t - 1/2gt²] ĵ

In the question, h= 3;

g in ft/s² = 32 ft/s² and Vo = 100 miles per hour

Let's convert Vo to ft/s

1 mile/h = = 1.467 ft/s

So, 100 miles/h = 100 x 1.4667 ft/s = 146.67 ft/s

Plugging it into the →r(t) equation to obtain;

→r(t) = (146.67Cos θ)tî + [3 + (146.67sinθ)t - (32/2)t²] ĵ

Using the general form of;

→r(t) = xî + yĵ

Thus; x = (146.67Cos θ)t and

y = [3 + (146.67sinθ)t - (32/2)t²]

In x; t = x/(146.67 Cosθ)

So plugging this value of t into the equation for y, we obtain;

y = [3 + [(146.67sinθ) (x/(146.67 Cosθ))] - [(16)(x/(146.67 Cosθ)²]

y = 3 + xtanθ - 16x²/(146.67 Cosθ)²

From the question, our y = the height of the field fence while x is the distance from the home plate.

Thus, y = 10 ft and x = 400ft.

Plugging them into the equation, to obtain;

10 = 3 + 400tanθ - 16(400)²/(146.67 Cosθ)²

10 - 3 = 400tanθ - (119/Cos²θ)

7 = 400tanθ - (119/Cos²θ)

From trigonometric identities, we know that, 1/Cos²θ = Sec²θ

Thus,

7 = 400tanθ - 119Sec²θ

Again from trigonometric identities,

Sec²θ = 1 + Tan²θ

Thus 7 = 400tanθ - 119(1 + Tan²θ)

Arranging this to get;

119tan²θ - 400tanθ + 126 = 0

Using quadratic equation to solve,

tanθ = 0.3518

So,θ = tan^(-1) 0.3518

So,θ = 19.382° or approximately, 19.4°

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
