A boat traveling moving at 21.00 m/s North is a river. The current in the river is moving west to east at 4.390 m/s. What is the relative velocity of the boat as it travels in the river? Select one: a. 16.61 m/s at 45.00 degrees b. 21.00 m/s at 90.00 degrees c. 21.45 m/s at 78.19 degrees d. 25.39 m/s at 34.00 degrees

Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)What is her speed with respect to the starting point on the bank? b.)How long does it take her to cross the river?

The resultant velocity of the airplane is a. 112.805 m/s, 12.80° south of east O b. 135 m/s, 12.80° south of east O c. 112.805 m/s, 12.80° east of south O d. 85 m/s, 12.80° south of east If a vector Á has components Ax = -2 and A, = +3, then A lies in the O a. 4th quadrant O b. 1st quadrant O c. 2nd quadrant O d. 3rd quadrant

A boy, who can swim at 2.5km/h in still water, wants toswim directly across a riverand land directly North of their starting point.The current in the river of 2.0 km/h [W].a. What direction must the swimmerhead? [E37°N]b. If the river is 150 m wide, how long willit take them to cross the river? [0.10 h]

A projectile is projected from the origin with a velocity of 30.0 m/s at an angle of 45.0 degrees above the horizontal. What is the range of the projectile? O a. 144 m O b. 91.8 m O c. 48.5 m O d. 86.2 m

*62. mmh A ferryboat is traveling in a direction 38.0° north of east with a speed of 5.50 m/s relative to the water. A passenger is walking with a velocity of 2.50 m/s due east relative to the boat. What is the velocity (magnitude and direction) of the passenger with respect to the water? Determine the directional angle relative to due east.

A pilot wants to fly north. The plane has an airspeed of 350 km/h. There is a 50 km/h windblowing to the west.a. What direction does the plane need tohead? [E82°N]b. What is the plane’s velocity relative tothe ground? [346 km/h [N]]

A person can row a boat at 4.00 mi/h in still water. They need to cross ariver that is 1.50 mi wide with a current flowing at 2.60 mi/h. a. Draw a labeled picture of the situationb. In order to go straight across, what angle upstream should they point theboat?c. What is the persons speed with respect to the starting point?d. How long does it take them to cross the river?e. Let’s assume they angle the boat at 60o upstream. How far upstream ordownstream from their starting point will they end up when reaching theopposite bank?
