Chinook salmon are able to move upstream faster by jumping out of the water periodically; this behavior is called porpoising. Suppose a salmon swimming in still water jumps out of the water with a speed of 6.26 m/s at an angle of 30°, sails through the air a distance L before returning to the water, and then swims a distance L under water at a speed of 3.70 m/s before beginning another porpoising maneuver. Determine the average speed of the fish.
A snowmobile is originally at the point with position vector 30.5 m at 95.0° counterclockwise from the x-axis, moving with velocity 4.89 m/s at 40.0°. It moves with a constant acceleration 1.72 m/s2 at 200°. After 5.00 s have elapsed, find the following. (Express your answers in vector form.) (a) its velocity vector. (b) its position vector.
Suppose that a northward-flowing river is w = 2a wide, where a = 0.5 mi, and that its midstream velocity is v₁ = 12 mi/h. A swimmer starts at the point (-a,0) on the west bank and swims due east (relative to the water) with constant speed Vs = 4 mi/h. The velocity VR at which the water flows increases as one approaches the center of the river, and is given ×4 in terms of distance x from the center by VR = VO a4 the river. Find how far downstream the swimmer drifts as he crosses The swimmer drifts mi downstream.
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?
A car travels due east with a speed of 39.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 61.0° with the vertical. Find the velocity of the rain with respect to the following reference frames. (a) the car (b) the Earth Step 1 RC RE (a) To solve for the velocity of the rain relative to the car each moving relative to the Earth, we use the analogy of two objects moving relative to the Earth, each with constant velocity. Let v be the velocity of the rain relative to the car, V the velocity of the rain relative to the Earth, and VCE the velocity of the car relative to the Earth. Following the pattern of subscripts illustrated in the equation for two objects moving relative to the Earth, VAB = V VAE E-VBE we find that the velocity of the rain relative to the car is v with x- and y-components given by the following equations.

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.
