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...
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...
