A 321-kg boat is sailing 10.0° north of east at a speed of 2.00 m/s. 30.0 s later, it is sailing 33.0° north of east at a speed of 4.10 m/s. During this time, three forces act on the boat: a 32.3-N force directed 10.0° north of east (due to an auxiliary engine), a 23.9-N force directed 10.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...

009 (part 1 of 3) 10.0 points A proton travels with a speed of 4.8×106 m/s at an angle of 96◦ west of north. A magnetic field of 4.6 T points to the north. Find the magnitude of the magnetic force on the proton. (The magnetic force experienced by the proton in the magnetic field is proportional to the component of the proton’s velocity that is perpendicular to the magnetic field.) Answer in units of N. 010 (part 2 of...

Jaya drives 340.0 m due east, which takes her 15 seconds. She turns and travels 540 m due north while traveling at a constant 27.1 m/s. Then she turns and travels 210 m due east, which takes her 11.0 s. a) Draw a diagram showing Jaya's path. Label the path length of each leg of the journey. Draw the total displacement vector on the diagram. b) What is the total elapsed time for Jaya's journey? c) What was the path...
