A point charge of -2 µC is located at the origin. A second point charge of 6 µC is at x = 1 m, y = 0.5 m. Find the x and y coord

Soloha48 [4]

Answer:

x coordinate = -1.66 m

y coordinate is = -0.825m

Explanation:

Suppose z be the distance form the first charge and z + sqrt(1^2 +.5^2) be the distance from the second So z + sqrt(1+.25) = z + 1.12

We have k*2.0x10^-6/s^2 = k*6x10^-6/(s+1.12)^2

0.0356s^2 -0.019s-0.0897=0

s=1.876m

The angle of the line between the two charges is arctan(.5/1) = 26.6o

x coordinate = -1.876*cos(26.6) = -1.66m

y coordinate is -1.876*sin(26.6) = -0.825m

Starting at 48th Street, Dylan rides his bike due east on Meridian Road with the wind at his back. He rides for 20 min at 15 mph

Nezavi [6.7K]

Answer:

55 min

Explanation:

The missing question is: how long does the trip take?

First of all, we need to find the initial distance covered by Dylan. In the first part, he rides for

$t_1 = 20 min = \frac{1}{3}h$

at a speed of

v = 15 mph

therefore, the distance he covered is

$d = v t_1 = (15)(\frac{1}{3})=5 mi$

Then Dylan stopped for a time of

$t_2 = 5 min = \frac{5}{60}=\frac{1}{12}h$

Finally, on the way back, Dylan covered again this distance but travelling at a new speed of

v = 10 mph

So, the time he took is

$t_3 = \frac{d}{v}=\frac{5}{10}=\frac{1}{2}h = 30 min$

So, the total time of the trip was

$t=t_1 + t_2 + t_3 = 20 min + 5 min + 30 min = 55 min$
