I could use some help with the following Physics question.

Suppose you walk 18.0 m straight west and then 25.0 m straight north. (If you represent the two legs of the walk as vector displacements A and B, as in the figure below, then this problem asks you to find their sum R = A + B.) A + B = R R N B W E S A How far, in meters, are you from your starting point? (Enter a number.) m What is the compass direction of a line connecting your starting point to your final position measured in degrees west of north? (Enter a number.) A ball is kicked with an initial velocity of 11 m/s in the horizontal direction and 21 m/s in the vertical direction. (Assume the ball is kicked from the ground. For each answer, enter a number.) (a) At what speed (in m/s) does the ball hit the ground? m/s (b) For how long (in s) does the ball remain in the air? (c) What maximum height (in m) is attained by the ball? m
