Velocity and force.
An airplane flying toward 0 degrees at 100 km/h is being blown toward 90 degrees at 40 km/h. What is the resultant velocity of the plane?
Three people are pulling on a tree. The first person pulls with 15 N at 65 degrees; the second with 16 N at 135 degrees; the third with 11 N at 195 degrees. What is the magnitude and direction of the resultant force on the tree?
I keep getting confused on how to set them up.
Back to back posts merged. The following information has been added:
For the force problem I got 27.04 N, NW at negative 54.85 degrees.
For the velocity problem I got 107.7 km/h at 21.8 degrees. At least I tried.
