Question
Please help me solve.
a. Vector a has components ax = 6 m/s2 and ay = -13 m/s2. What is the direction of a? Give the angle "clockwise" from the +x axis.
b. What is the magnitude of your total displacement if you have traveled due west with a speed of 20 m/s for 125 s, then due south at 15 m/s for 65 s? (in m)
c. You will be hiking to a lake with some of your friends by following the trails indicated on a map at the trailhead. The map says that you will travel 40 mi directly north, then 30 mi in a direction 70
Explanation / Answer
a) tan-1(13/6) is theta the angle from x axis in clockwise direction
b)sqrt(((20*125)^2)+((15*65)^2)) metres
c)
