### physics problem pls help me?

An airplane starting from airport A flies

189 km east, then 574 km at 74.1◦ west

of north, and then 462 km north to arrive

finally at airport B. The next day, another

plane flies directly from A to B in a straight

line.

In what direction should the pilot travel

in this direct flight? Use counterclockwise

as the positive angular direction from due

east, between the limits of −180◦

and 180◦.

Assume there is no wind during these flights.

Answer in units of ◦

How far will the pilot travel in this direct

flight?

Answer in units of km.

A hiker makes four straight-line walks

A 11 km at 262 ◦

B 31 km at 192 ◦

C 18 km at 97 ◦

D 31 km at 22 ◦

in random directions and lengths starting at position (41 km, 41 km),

How far from the starting point is the hiker

after these four legs of the hike? All angles

are measured in a counter-clockwise direction

from the positive x-axis.

Answer in units of km.

A record of travel along a straight path is as

follows.

1. Start from rest with constant acceleration of 2.56 m/s^2 for 13 s.

2. Constant velocity for the next 2.74 min.

3. Constant negative acceleration

−9.39 m/s^2 for 3.48 s.

What was the total displacement for the

complete trip?

Answer in units of km.

What was the average speed for the complete

trip?

A car starts from rest and travels for 5.4 s with a uniform acceleration of 3.8 m/s^2. The driver then applies the brakes, causing a uniform acceleration of −1.7 m/s^2.

If the brakes are applied for 2.5 s, how fast is the car going at the end of the braking

period?

How far has it gone?

A young woman named Kathy Kool buys a sports car that can accelerate at the rate of 4.08 m/s^2. She decides to test the car by drag racing with another speedster, Stan Speedy. Both start from rest, but experienced Stan leaves the starting line 1.11 s before Kathy. Stan moves with a constant acceleration of

2.73 m/s^2 and Kathy maintains an acceleration of 4.08 m/s^2.

Find the speed of Stan’s car at the instant she overtakes him.

Find Kathy’s speed at that instant.

Answer in units of m/s.

An engineer in a locomotive sees a car stuck on the track at a railroad crossing in front of the train. When the engineer first sees the car, the locomotive is 350 m from the crossing and its speed is 13 m/s. If the engineer’s reaction time is 0.32 s, what should be the magnitude of the minimum deceleration to avoid an accident?

Answer in units of m/s^2.
