The speed of a boat in still water is V. A river flows with a speed of v,. The boat travels distance of 14 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the V and V₁ Hint: Velocity = displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "vo" and "v,": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. Equation 1 (downstream): Equation 2 (upstream): Solve for: = vb Write an algebraic expression; do not use numerical values except for the angles. You can enter subscripts by selecting the MathType popup button (red radical) in the answer box. To enter subscripts, press the first right-facing arrow in menu of the popup. For degrees, enter the value and add the degree symbol symbol (o) by pressing the right-facing arrow next to the division symbol. miles/hour miles/hour vb Downstream positive Vr Upstream negative vr = 14 miles/hour =-7 miles/hour

A traveler first drives 22.0 km east, then 27.0 km southeast, and finally 10.7 km south. Find the traveler's total displacement.    (Confused with how to get the Direction answer for this problem. Displacement is 50.75 km.)

A woman stands at the edge of a cliff and throws a rock horizontally over the edge with a speed of v, = 19.5 m/s. The rock leaves her hand at a height of h = 49.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the rock leaves the hand. (a) What are the coordinates of the initial position of the rock? (Enter your answers in m.) m Yo = (b) What are the components of the initial velocity? (Enter your answers in m/s.) Vox = m/s Voy m/s
