Suppose waves move in the open ocean at a speed of v1 = 4.5 m/s, at an angle of ?1 = 41o to the normal to the shore, see figure. At some distance from the shore, the ocean floor rises and the speed of the waves drops from v1 to v2 = 3.0 m/s. At what new angle to the normal do the waves now approach the shore (in degrees)? |

A dolphin (Dolphin A) is swimming under the ocean at a speed of 4.87 m/s, emitting sonar sound wave at a frequency of 1222 Hz. The speed of sound waves under the ocean is 5518.8 km/h. Another dolphin (Dolphin B), located away is such that the two dolphins move towards each other. If Dolphin B is moving at 7.31 m/s, calculate the frequency that would be detected by a receiver attached to Dolphin B as the two fish swim towards...
Particle 1, with a charge q1=3.60 microcoulombs and a speed v1=862 m/s, travels at right angles to a uniform magnetic field. The magnetic force it experiences is 4.25 x 10-3 N. Particle 2, with a charge q2=53.0 microcoulombs and a speed v2= 1.30 x 103 m/s, moves at an angle of 55.0 degrees relative to the same magnetic field. At what angle relative to the magnetic field must particle 2 move if the magnetic force it experiences is to be...
<HW 2.2 Properties of Ocean Waves How fast are the waves traveling? Express the speed e in meters per second using three significant figures. Review Constants Periodic Table A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.10 s for the boat to travel from its highest point to its lowest, a total distance of 0 670 m. The...
A car with a mass of 1040 kg and a speed of v1 = 15.0 m/s approaches an intersection, as shown in the figure. A 1270 kg minivan traveling at v2 is heading for the same intersection. The car and minivan collide and stick together. The direction of the wreckage after the collision is theta=40.0 degrees above the x axis. Part A) Find the initial speed of the minivan, assuming external forces can be ignored (in m/s). Part B) Find...
A chauffeur heads south with a steady speed of v1 = 22.0 m/s for t1 = 3.00 min, then makes a right turn and travels at v2 = 25.0 m/s for t2 = 3.00 min, and then drives northwest at vz = 30.0 m/s for tz = 1.00 min. For this 7.00-min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.)...
A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?
A train begins at the origin and moves at constant speed v1=16.1 m/s toward another train which is initially at rest at a distance d=108 m from the first train. If the second train has an acceleration of magnitude a2=1.29 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=15.2 m/s toward another train which is initially at rest at a distance d=164 m from the first train. If the second train has an acceleration of magnitude a2=1.02 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=13.1 m/s toward another train which is initially at rest at a distance d=264 m from the first train. If the second train has an acceleration of magnitude a2=1.22 m/s2 toward the first train, how far does the first train move before the trains collide?
