Question
1. a car travels due east at a speed of 48.0 km/h. raindrops are falling at a constant speed vertically with respect to earth. the traces of the rain on the side of the car windows make an angle of 68.0 with the vertical. find the velocity of the rainwith respect to the following reference frames. (enter the magnitude of the velocity)
A) the car (m/s)
B) the earth (m/s)
2. The coast gaurd cutter detects an unidentified ship at a distance of 23.0 km in the direction of 15 degrees east of north. the ship is traveling at 20.0 km/h on the course at 40 degrees east of north. the coast gaurd wants to sent a speedboat to intercept and investigate this vessel.
A) if the speedboat travels at 46.0 km/h, in what direction should it head? express the direction as a compass bearing with respects of due north (degrees east of north)
B) find the time required for the cutter to intercept the ship (min)
Explanation / Answer
use the concept of relative velocity.......
