Two piers, A and B, are located on a river; B is 1500 m downstream
from A (Fig.). Two friends must make round trips from
pier A to pier B and return. One rows a boat at a constant speed of
4.00 km>h relative to the water; the other walks on the shore at a constant
speed of 4.00 km>h. The velocity of the river is 2.80 km>h in the
direction from A to B. How much time does it take each person to make
the round trip?

- An electron, with an initial horizontal velocity of magnitude 2.44 × 109 cm/s, travels into the region between two horizontal metal plates that are electrically charged. In that region, it travels a horizontal distance of 2.18 cm and has a constant downward acceleration of magnitude 3.13 × 1017 cm/s2 due to the charged plates.

- For this problem, you can think of the jet stream as a river of air. Across the United States, the jet stream usually moves from west to east. We will assume that the jet stream is moving in its usual direction at 9.00 x 101 km/hr. On a particular day, you need to pilot a plane from one city to another that is 4.50 x 102 km directly to the south. The top speed of the aircraft in still air is 285 km/hr. (a) Make a sketch to represent what is happening in this problem. Label all quantities that you know. (b) Using cardinal directions (north, east, south, west) to give a heading, which direction should you aim the plane to reach the city directly to the south at top speed? (c) How fast (in km/hr) would you be moving relative to the ground? (c) How much time (in hr) will it take you to reach your destination?An electron, with an initial horizontal velocity of magnitude 4.57 × 109 cm/s, travels into the region between two horizontal metal plates that are electrically charged. In that region, it travels a horizontal distance of 2.25 cm and has a constant downward acceleration of magnitude 2.35 × 1017 cm/s2 due to the charged plates. Find (a) the time required by the electron to travel the 2.25 cm and (b) the vertical distance it travels during that time. Also find the magnitudes of the (c) horizontal and (d) vertical velocity components of the electron as it emerges.The take off speed of a military aircraft from an aircraft carrier is approximately 170 mi/hr relative to the air. They acquire this speed through a combination of a catapult system present on the aircraft carrier and the aircraft's jet propulsion system. A common strategy is to head the carrier and the plane into the wind. If a plane is taking off from an aircraft carrier which is moving at 40 mi/hr into a 20 mi/hr headwind, then what speed relative to the deck of the aircraft carrier must it obtain to takeoff? Draw your vectors.
