3) 35 pts. Water in a river flows with a component downstream (x-direction) of 6 m/s and a component across the stream (y -direction) of 4 m/s. A boat is attempting to cross the river. The velocity of the boat relative to the water is 20 m/s at an angle of 70 degrees with respect to the x-axis. Determine the velocity of the boat relative to the shore.

1. A boat can travel at 25 mph wrt the water. If the boat is in a river that flows East at 10 mph, and we would like the boat to go straight across the river, at what angle should the boat point and what is its speed relative to the shore? 2. A boat travels at 25 mph wrt the river, 20°west of north. The river flows east at 10 mph. What is the velocity of the boat wrt...

A river flows due east at 1. 50 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water. (a) What is the velocity of the boat relative to the shore? (b) If the river is 300 m wide, how far downstream has the boat moved by the time it reaches the north shore?

A river flows due east at 2.69 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 12.2 m/s due north relative to the water. What is (a) the magnitude (m/s) and (b) the direction (degrees east of north) of the boat’s velocity relative to shore? (c) If the river is 324 m wide, how far (m) downstream has the boat moved by the time it reaches the north shore?
