A boat can travel 2.85 m/s in still water. If the boat points its bow directly across stream whose current is .95 m/s, what is the velocity of the boat relative to the shore?

  • Physics -

    x speed = .95
    y speed = 2.85

    speed magnitude = sqrt(.95^2 + 2.85^2)
    = 3.00

    tan angle to shore = 2.85/.95
    A = 71.6 degrees from shoreline
