A river has a steady current of 0.50 m/s [E]. A person can swim at 1.2 m/s in still water. The person swims upstream 1.0 km and then back to the starting point. How long does the trip take?(b) Will the time change if he swims downstream 1.0 km and then back instead? Explain your reasoning.(c) How much time is required to complete the same trip in still water? Why does the trip take longer when there is a current?

At one instant, a bicyclist is 50 m due east of a park's flagpole, going due south with a speed of 18 m/s. Then, 13 s later, the cyclist is 45 m due north of the flagpole, going due east with a speed of 13 m/s. For the cyclist in this 13 s interval, what is the displacement (m) and direction north of west, average velocity (m/s) and direction north of west and the average acceleration and direction north of east?
The water in a river flows uniformly at a constant speed of 2.27 m/s between parallel banks 69.3 m apart.

A boat is moving atv12kph is crossing a river 500 m wide in which a current is flowing at 4 kph. What must be its direction west of north for it to reach a point on the other side of the river from its starting point? What is the value of the velocity of the boat relative to the water?
Hello, (a) In what direction would the ship in Exercise 3.57 have to travel in order to have a velocity straight north relative to the Earth, assuming its speed relative to the water remains 7.00 m/s (b) What would its speed be relative to the Earth?fully is what you're asking for. Exeecise 3.57 is provided below: A ship sets sail from Rotterdam, The Netherlands, heading due north at 7.00 m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0º north of east. What is the velocity of the ship relative to the Earth?
Most important in an investigation of an airplane crash by the U.S. National Transportation Safety Board is the data stored on the airplane’s flight-data recorder, commonly called the “black box” in spite of its orange coloring and reflective tape.The recorder is engineered to withstand a crash with an average deceleration of magnitude 3450 g during a time interval of 6.49 ms. In such a crash, if the recorder and airplane have zero speed at the end of that time interval, what is their speed at the beginning of the interval?
A particle moves down a horizontal route that begins 5 feet to the right of a specific point P with an initial velocity of 4 feet per second. Another particle is going along the same route, beginning 3 feet to the left of P with an initial velocity of 8 feet per second. Consider that the accelerations of the two particles are a1(t) = 2t 3 and a2(t) = 2t 5, respectively. Will the particles collide? Justify your response
A spacecraft is observed to be at a location < 200 , 300 , -400 > m relative to an origin located on a nearby asteroid, and 5 seconds later is observed to be at location < 340 , 80 , -540 > m. (a) What is the average velocity of the spacecraft during this interval?v→avg = m/s (b) What is the average speed of the spacecraft during this period?|v→avg|= m/s (c) What is the unit vector in the direction of the average velocity?v^=
A sailboat sails from Marblehead Harbor directly east for 45 nautical miles, then 60 degree south of east for 20 nautical miles, returns to an easterly heading for 30 nautical miles, and sails 30 degreeeast of north for 10 nautical miles, then west for 62 nautical miles. At that time the boat becomes becalmed and the auxiliary engine fails to start. The crew decides to notify the Coast Guard of their position. What is their position?
A glider is initially moving at a constant height of 3.76 m. It is suddenly subject to a wind such that its velocity at a later time t can be described by the equation v(t) = 16.18 − 7.78(1 + t) + 0.70t3, where v and its components are in meters per second, t is in seconds, and the z axis is perpendicular to the level ground. (a) What was the initial velocity of the glider? (Express your answer in vector form.) vi = m/s(b) Write an expression for the acceleration of the glider in component form when t = 2.14 s. (Express your answer in vector form.) a(t = 2.14 s) = m/s2
On a spacecraft two engines fire for a time of 389 s. One gives the craft an acceleration in the x direction of ax = 3.41 m/s^2, while the other produces an acceleration in the y direction of ay = 7.34 m/s^2. At the end of the firing period, the craft has velocity components of vx = 1860 m/s and vy = 4290 m/s. Find the (a) magnitude and (b) direction of the initial velocity. Express the direction as an angle with respect to the +x axis.
Two canoeists, A and B, live on opposite shores of a 300.0 m wide river that flows east at 0.80 m/s. A lives on the north shore and B lives on the south shore. They both set out to visit a mutual friend X who lives on the north shore at a point 200.0 m upstream from A and 200.0 m downstream from B. Both canoeists can propel their canoes at 2.4 m/s through the water. How much time must canoeist A wait after canoeist B sets out so that they both arrive at X at the same time? Both canoeists make their respective trips by the most direct routes
In an experiment to determine the viscosity of some oil, a ball is dropped into the oil. The position of the ball is given by the formula y(t) = A + Bt +C e−Dt, where y is given in m, and t is the time in s. At t = 0, y(0) = 0.1 m, the y component of the velocity is zero and the y component of the acceleration is ay(0)= 0.04 m/s2. As t approaches infinity, the y component of the velocity approaches vy(∞) = 0.5 m/s. What is the value of A, C, and D? Please show work so I can understand.
