Figure 10: River B VB VR A boat crosses a river of width 23.4 meters. The boat was traveling with a speed of 5.2 meters per second relative to the water. The river was moving to the right with a speed of vr = 3.5 m/s relative to the shore. The boat was traveling at an angle of theta = 0 = 56.5 degrees relative to the water away from the near shore. In other words, theta e is the angle between the velocity of the boat relative to the water and the velocity of the water relative to the shore. The situation is shown in figure 2, above. The boat left the near shore at point A and reached the opposite shore at point B (both indicated in the diagram above). Assume the shores of the river are parallel and straight, and all velocities are constant. Point B is a distance d downstream (to the right) from Point A. Calculate the distance d in meters.

How long should it take the voices of astronauts on the Moon to reach the Earth? Assume that the only significant time is the transit time from the Earth to the Moon, at the speed of light. Suppose that the astronaut on the surface of the Moon, the receiver on the surface of the Earth, and the centers of the Earth and the Moon are aligned. The distance between the centers of the Earth and the Moon is 384×103km, the radius of the Earth is 6.38×103km, the radius of the Moon is 1.74×103km.

The graph above represents the data from Activity 3 in this week's lab describing the position of a moving cart as a function of time. The equation for the best-fit line for this position vs. time graph is y = 3.9609x + 0.1739. What is the speed of the cart? [All the quantities are measured in standard units. Do not include units in your answer.]
Two speedboats are traveling at the same speed relative to the water in opposite directions in a moving river. An observer on the riverbank sees the boats moving at V₁0 = 4.90 m/s and V20 =5.90 m/s. (a) What is the speed of each boat relative to the river? Vbr m/s (b) How fast is the river moving relative to the shore? m/s Vro
A boat is docked on the southern shore of a swiftly moving river that is 262.0 m wide. The river flows from east to west with a speed of 4.00 m/s relative to the shore. There is a dock located upstream on the northern side of the river at an angle of 57.0∘57.0∘ relative to the shore (i.e. north of east). The boat is able to travel at a speed of 6.50 m/s relative to the water. If the boat travels directly to the dock on the northern shore at a constant speed, how long does it take to get there?

Taking north as positive and south as negative for all reference frames, suppose Mayor Adams is riding a southbound train to New York City traveling at 40 m/s relative to the ground, while Governor Hochul is riding a northbound train to Albany at 33 m/s relative to the ground. A) What is the velocity of Mayor Adams in Governor Hochul's reference frame (i.e. in the reference frame where Governor Hochul isn't moving)? B) What is the velocity of Governor Hochul in Mayor Adams reference frame? C) To his surprise Mayor Adams observes a groundhog running along the aisle towards the back of the train with a speed of 2 m/s relative to the train. What is the velocity of the groundhog in Governor Hochul's reference frame? D) What is the groundhog's velocity in the reference frame of someone standing at the train station?

A ladder 5.0 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 3.0 m from the wall, and the top of the ladder is 4.0 m above the floor. The spaceship moves past the Earth with a speed of 0.90c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor as seen by an observer on Earth.
