Homework Statement
Find the x-coordinate of the first point in the region where intersects . Give your answer to 6 significant figures.
Homework Equations
x_1=x_0- (f(x)/f'(x))
The Attempt at a Solution
I equated the two equations and got:
0=tanx-5x
I also looked at the graph...
Homework Statement
Ship A is located 3.5 km north and 2.8 km east of ship B. Ship A has a velocity of 22 km/h toward the south and ship B has a velocity of 40 km/h in a direction 37° north of east.
At what time is the separation between the ships least?
Homework Equations...
I also tried the vector equations:
(V_ax+V_ay)=(V_abx+V_aby)+(V_bx+V_by)
or
(-15.55i+15.55j)=(V_abx+V_aby)+(-22.22i+18.64j)
so when I separate the equations I get:
-15.55=V_abx-22.22
V_abx=6.67i
15.55=V_aby+18.64
V_aby=-3.09
therefore V_ab=(6.67i+3.09j)
so the...
So I'm looking for V_ab( velocity of a with respect to b), therefore the velocity of a(V_a) is equal to the velocity of b(V_B) plus the velocity of a with respect to b(V_ab) and I know both a and b so:
V_a=V_ab+V_b
22=V_ab+29
-7=V_ab
however is is showing as incorrect(I used 7 since...
Homework Statement
Two ships, A and B, leave port at the same time. Ship A travels northwest at 22 knots and ship B travels at 29 knots in a direction 40° west of south.
(a) What is the magnitude the velocity of ship A relative to B?
(b) What is the direction of the velocity of ship A...
