1) Find resultant r of given forces.
f1 acting with magnitude of 5 N and f2 acting at the angle of 45° to f2 with the magnitude of 8 N. (Suppose f1 acts in positive x direction.)
2. The airplane heading due east has the velocity of 195 miles per hour. The wind is blowing from north at 42 miles per hour. Determine resultant velocity of airplane? Suppose that east lies in direction of positive x-axis and north in direction of positive y-axis.
