Find the resultant vector? 1/6 of 240 m/s directed east ?= 1/4 of 240 m/s 1/5 of 250 degrees south of west
1 Answer
Amplitude:
Direction:
Explanation:
Because
"Find the resultant vector? 40 m/s directed east + 60 m/s 50 degrees south of west" (I also assumed the question mark in the middle of the question was intended to indicate calculating the vector sum of the 2 velocities.)
Find components of the 2nd velocity in the East-West and North-South directions:
East-West
#" "60 m/s*cos50 = 38.57 m/s "West"#
North-South#" "60 m/s*sin50 = 45.96 m/s "South"#
Since the first velocity is Eastward it can be combined with the East-West component of the 2nd given velocity. Since they are opposite directions, subtraction is required.
So now we need to combine
Magnitude:
Direction:
