A boat travelling at 30km/hr relative to water is headed away from the bank of a river and downstream. The river is 1/2 km wide and flows at 6km/hr. The boat arrives at the opposite bank in 1.24 min. I calculated the perpendicular component of the boat relative to the water as...

if the water in the river moves downstream at 4mi/hr heading the boat straight across the river, what direction will the boat move relative to the shore? i dont want the answer... i want someone to explain. i wanna learn

**physics - relative motion**

A ferryboat, whose speed in still water is 4.00m/s, must cross a river whose current is 3.00m/s. The river runs from west to east and is 128m wide. The boat is pointed north. a) If the boat does not compensate for the flow of the river water and allows itself to be pushed off ...

20. Miguel is driving his motorboat across a river. The speed of the boat in still water is 11 mi/h. The river flows directly south at 2 mi/h. If Miguel heads directly west, what are the boat’s resultant speed and direction?

**Physics - Relative velocity**

A barge is heading directly across a river at35km/h while you are walking on the barge at 4km/h in the same direction as the barge is heading. The current is flowing downstream at 1.4km/h. a) What is your velocity relative to the shore? (7.6km/h) b) What would you velocity be ...

Miguel is driving his motorboat across a river. The speed of the boat in still water is 10 mi/h. The river flows directly south at 3 mi/h. If Miguel heads directly west, what are the boat’s resultant speed and direction? Round answers to the nearest tenth.

Two people take identical jet skis across a river, traveling at the same speed relative to the water. Jet ski A heads directly across the river and is carried downstream by the current before reaching the opposite shore. Jet ski B travels in a direction that is 35° upstream, ...

a 3.5 kg dog stands on a 21 kg flatboat at distance D = 6.1 m from the shore. It walks 2.3 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore. I thought i have the right equation but my...
