Airplane flight An airplane flying at a speed of $360 \mathrm{mi} / \mathrm{hr}$ flies from a point $A$ in the direction $137^{\circ}$ for $30$ minutes and then flies in the direction $227^{\circ}$ for $45$ minutes. Approximate, to the nearest mile, the distance from the airplane to $A$.

Choose the word or phrase that is closest in meaning to the word in capital letters.

PARALLEL
(A) never crossing
(B) tied together
(C) unequal
(D) immovable

Use your TI-83/89 to analyze the paper airplane flight distance data from the mentioned activity.

First, enter the data into your calculator and explore the data graphically. Does it appear that at least one of the means is different from the other means?

An air freight company has determined that its cost per flight of delivering $x$ parcels is

$$C(x)=875+0.75 x$$

Prove these statements: $(a)$ As long as you can neglect the effects of the air, if you throw anything vertically upward, it will have the same speed when it returns to the release point as when it was released. $(b)$ The time of flight will be twice the time it takes to get to its highest point.

The Boeing 727 aircraft of Example $9.8$ cruises at $520 \mathrm{mph}$ at $33,000 \mathrm{ft}$ altitude on a standard day. Calculate the cruise Mach number of the aircraft. If the maximum allowable operating Mach number for the aircraft is $0.9$, what is the corresponding flight speed?

Leaving Westwood at 1:00 P.M., Coretta flew to Bay View. The flight took 1.5 hours, but the time zone for Bay View is 2 hours earlier than Westwood's zone. What time was it in Bay View when Coretta landed?

Calculate the minimum $\Delta v$ required to place a satellite already in Earth's heliocentric orbit (assumed circular) into the orbit of Venus (also assumed circular and coplanar with Earth). Consider only the gravitational attraction of the Sun. What time of flight would such a trip take?

Do the given.

Determine how long the projectile is in flight and the horizontal distance covered.

Tiger is playing golf. He hits a golf ball from the ground at an angle of $60^{\circ}$ with respect to the ground at velocity $150 \mathrm{ft}$ per sec.

A ball is thrown into the air with an initial velocity of 100 feet per second at a 20 degrees angle of elevation. What is the horizontal component of the velocity? What is the horizontal displacement of the ball during its first three seconds of flight? (Neglect the effect of air resistance.)
