Sheena can row a boat at 3.00mi/h in still water. She needs to cross a river that is 1.20mi wide with a current flowing at 2.00 milh. 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. What is her speed with respect to the starting point on the bank? mi/h Sheena can row a boat at 3.00mi/h in still water. She needs to cross a river that is 1.20mi wide with a current flowing at 2.00mi/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. How long does it take her to cross the river? minutes Sheena can row a boat at 3.00mi/h in still water. She needs to cross a river that is 1.20mi wide with a current flowing at 2.00mi/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. How far upstream or downstream from her starting point will she reach the opposite bank? If upstream, enter a positive value and if downstream, enter a negative value. Sheena can row a boat at 3.00mi/h in still water.
