Relative velocity Definition and 408 Threads

Hey I’m just having a bit of trouble with this relative velocity question: This is what I've got so far: Work so far. I think I've gotten a part a right, and I've made a start on a part b, but I am pretty much lost on part b (i) and (ii). Any help would be appreciated. (v =...

Hey I need a little help with this (B) question: Find: (I) P and Q (II)How long will it take her to swim in a straight line back to the original starting point. Ive done some of the basics here, which i know to be right, including the answers to part 1 - when i tried to bring it further...

Id be very grateful for any help with this relative velocity question: To a man walking North at 4m/s, a constant wind appears to have a speed f 3m/s. The man then changes direction, and when he is walking West at 3m/s the wind appears to have a speed of 4 m/s. There are two possible wind...

How long does it take an automobile traveling in the left lane at 60.0 km/hr to pull along side a car traveling in the right lane at 40.0 km/hr if the cars' front bumpers are initially 100 m apart? I know the velocity of the car in the left is 60 and the velocity of the car on the right is...

Can someone please explain in relative velocity please?

river current = 22 m/s [South] width of the river from one side to the other = 325m speed of person swiming = 47 m/s if the person travels 47 m/s [E 7.5 degrees S] then how far up or down the stream will he end up when he reaches the other side?

Here the question, A swimmer wants to cross a river, from point A to point B. The distance d_1 (from A to C) is 200 m, the distance d_2 (from C to B) is 150 m, and the speed v_r of the current in the river is 5 km/h. Suppose that the swimmer makes an angle of theta=45 deg. (0.785 radians)...

A small air plane is traveling at a velocity relative to the air of 100km/h [E]. A wind from the north is blowing at 20km/h. (a) Determine the position of the airplane after 2.5 h of this motion. (b) Find the average velocity of the airplave during the 2.5 h interval. Thanks a Lot...
