A farmer builds three sections of a fence as shown in the figure where L = 10.00 m, and gets tired. Walking straight back to where he started, how far did he have to go?
d = x +L
by pythogorean theorem
L^2 = x^2 + (L/2)^2
L^2 = x^2 + (L^2)/4
4L^2 = 4x^2 + L^2
3L^2 = 4x^2
given = L = 10 m
3*10^2 = 4x^2
x = 8.67 m

Measurement "Spraying for Weeds" Farmer Jones is spraying his boundaries and fence lines with Weed-killer. He has to spray along the outside fence line of the fields with a back-pack sprayer One litre of Weed-killer will cover 26 metres of fence line. The field measurements are shown below. Field B can be assumed to be a semicircle Field B 170 m 33 m Fleld A 65 36 m 42 m YOUR TASKS: A) If he walks at 1.2 km/hr how...
Three point charges lie along a
straight line as shown in the figure below, where q1 = 5.94 µC, q2
= 1.41 µC, and q3 = -2.2 µC. The separation distances are d1 = 3.00
cm and d2 = 2.00 cm. Calculate the magnitude and direction of the
net electric force on each of the charges.
