+ Drag and drop your files or click to browse. Q4 (10 points) You are at a circular lake with radius 30 km, centered at the point(0,0). You want to travel from (30,0) to (-30,0). You will row from (30, 0) in a straight line to a point on the shore that is angle 8 radians around the lake from where you started, and then you will walk the rest of the way along the circular shore to (-30,0). Your...

A woman is on a lake in a rowboat located 1 mi from the closest point P of a straight shoreline (see the accompanying figure). She wishes to get to point Q, 10mi along the shore from P, by rowing to a point R between P and Q and then walking the rest of the distance. If she can row at a speed of 2mph and walk at a speed of 6 mph how should she pick the point R...

One afternoon, a couple hikes 55.0 % of the way around a circular lake, the radius of which is 2.60 km . They start at the west side of the lake and head due south to begin their hike. a) If the couple makes the trip in 3.8 hours , what is their average speed for the trip? b) What is the displacement for the couple's hiking trip? give your answer as an ordered pair, with magnitude first, followed by a comma, then...

a. Two cyclists racing on parallel roads maintain constant speeds of 30 mi/hr and 25 mi/hr. The faster cyclists crosses the finish line one hour before the slower cyclist. How long was the race (in miles)? b. Because Boat A travels 1.5 times faster than Boat B, Boat B was given a 1.5-hr head start in a race. How long did it take Boat A to catch Boat B? c. A plane flew into a headwind and made the outbound...

You walk for 6.44 km at a constant speed of 2.54 m/s due west, turn around, and then walk with an average speed of 0.440 m/s due east. From your starting point to your destination, the magnitude of your overall average velocity (!) is 1.25 m/s (due west). During the trip, how far east did you walk (i.e. how many meters due east have you been walking after making the turn)?

A particle is moving along a circular path having a radius of 5.4 in. such that its position as a function of time is given by @=sin 3t, where and the argument for the sine are in radians, and t is in seconds. Part A Determine the acceleration of the particle at 8 = 30. The particle starts from rest at 0 = 0° Express your answer to three significant figures and include the appropriate units.

A point starts at the location ( -7,0) and moves CCW along a circle centered at (0,0) at a constant angular speed of 2 radians per second. Lett represent the number of seconds since the point has swept out since it started moving. Draw a diagram of this to make sure you understand the context! a. Suppose the point has traveled for 0.2 seconds (t = 0.2). How many radians would need to be swept out from the 3-o'clock position...
