A man pushes a lawn mower with a force of 30 lb exerted at an angle of 30° to the ground. Find the horizontal and vertical components of the force. (Assume that the horizontal direction is positive and the vertical direction is negative.)

A sailboat floats in a current that flows due east at 9 m/s. Due to a wind, the boat's actual speed relative to shore is 9/3 m/s in a direction 30° north of east. Find the speed and direction of the wind. Let c represent the current; this means that c| is the speed of the moving water and c points in the direction of the moving water. Assume that the vector w gives the speed and direction of the wind and the vector v, gives the speed and direction of the sailboat relative to the shore. Which equation below represents w in terms of c and v,? O A. w=Vg + C O B. w=vg - c O C. w=Vg O D. w=vg -2•c The speed of the wind is V in the direction of
