A river is moving east at vWE = 2.29 m/s. A boat starts from the dock heading θ = 39.3 degrees north of west at vBW = 7.18 m/s, relative to the water. The river is w = 1130 m wide.

What is the speed of the boat, in m/s, with respect to Earth?


Answer :

Answer:

The speed of the boat, in m/s, with respect to Earth, is vBE = 7.52 m/s.

Explanation:

vBE = vBW + vWE

vBE = 7.18 m/s + 2.29 m/s

vBE = 7.52 m/s
