Q. Two forces are applied to a tree stump to pull it out of ground. Force A has a magnitude of 1790 newtons (N) and points 26 ° south of east, while force B has a magnitude of 4200 N and points due south. Using the component method find the (a) magnitude and (b) direction of the resultant force A + B that are applied to the stump. Identify the direction as a positive angle with respect to due east.

Q. A 0.025 kg golf ball moving at 21.0 m/s crashes throughout the window of a house in 2.0 10-4 s. After the crash, ball continues in the same direction with a speed of 10 m/s. assuming the force exerted on the ball by the window was constant, what was the magnitude of this force?
