Grade 12 Calculus Question

Ryan, in his canoe is trying to cross a river that is 150 m wide. If the water is flowing at a speed of 5 km/h and his boats still water speed is 10 km/h.

a. If he points his boat directly across the river what will the resultants speed of his canoe be?

b. How far downstream does Ryan end up?

c. If Ryan wants to end up directly across the river from where he starts, in what direction should he point his canoe?

A boat capable of making 6.0 km/h in still water is used to cross a river flowing at speed of 4.0 km/h. The boat is directed (from the perpendicular to the shore) in such a way that its resulting motion is straight across the river. At what angle (in o) must the boat be directed? What is the resultant speed relative to the shore?

A swimmer, capable of swimming at a speed of 1.80 m/s in still water (i.e., the swimmer can swim with a speed of 1.80 m/s relative to the water), starts to swim directly across a 1.70-km-wide river. However, the current is 1.18 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?

Sheena can row a boat at 2.40 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.60 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...

Tina can grow a boat at 2.60 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.90 mi/h. Not having her calculator she guesses that to go straight across she should head upstream at an angle of 25.0° from the direction straight across the river. What is her speed with respect to the starting point on the bank?

Two students are canoeing on a river. While heading upstream, they accidentally drop an empty bottle overboard. They then continue paddling for 1.2 h , reaching a point 2.2 km farther upstream. At this point they realize that the bottle is missing and, driven by ecological awareness, they turn around and head downstream. They catch up with and retrieve the bottle (which has been moving along with the current) 5.3 km downstream from the turn-around point. Part A) Assuming a...

A boat, whose speed in still water is 2.40 m/s , must cross a 285-m-wide river and arrive at a point 118 m upstream from where it starts (Figure 1). To do so, the pilot must head the boat at a 45∘ upstream angle. What is the speed of the river's current?

Swimming at 1.00 m/s relative to still water, a swimmer heads directly across a river of width 95 m. He arrives 35.0 m downstream from the point directly across the river from his starting point. (a) What is the speed of the current in the river?m/s (b) At what angle relative to the line perpendicular to the shore should he head to arrive at a point directly opposite his starting point? °

An athlete needs to get across a river. He must reach from point A on one bank to point B, which is directly across from point A on the opposite bank. If he wishes to minimize the total time T it would take to do so, at what angle upstreams (measured from the line AB) should he swim? Let his swimming／rowing speed relative to the water be 6.0 mi/h, and his running speed along the bank be 10 mi/h. The...
