You are riding in a boat whose speed relative to the water is 6.7 m/s. The boat points at some angle upstream on a river flowing at 1.4 m/s. The dock on the opposite shore of the river is at the location r = 55m and y = 28m relative to the starting point of the boat. (Figure 1) At what angle relative to the r axis must the boat be pointed in order to reach the other dock? Express your answer using two significant figures.

A baseball is thrown 25 m/s horizontally from a height of 5 m. What is its range (x)?

Town A lies 15 km north of town B. Town C lies 10 km west of town A. A small plane flies directly from town B to town C. What is the displacement of the plane? (Displacement has both distance and direction.)

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of  v0 = 17.0 m/s.  The cliff is h = 47.0 m above a flat, horizontal beach as shown in the figure. A student stands on the edge of a cliff with his hand a height h above a flat stretch of ground below the clifftop. The +x-axis extends to the right along the ground and the +y-axis extends up from the ground to the top of the cliff. The origin O of the coordinate plane is directly below the student's hand where the base of the cliff meets the flat ground. The student throws a stone horizontally rightward with initial velocity vector v0. The stone falls with a parabolic trajectory, hitting the ground with a velocity vector v that points down and right. Vector g points straight down. (a) What are the coordinates of the initial position of the stone? x0 =   m y0 =   m (b) What are the components of the initial velocity? v0x =   m/s v0y =   m/s (c) Write the equations for the x-…
