A boat sails in a direction 60 degrees north of east with a constant acceleration of 1.5 m/s^2, starting from rest. What are its northerly and easterly components of the velocity after 15 seconds?

Answer 1

V = a * t = 1.5[60] * 15 = 22.5m/s[60o.

X = 22.5*cos60 = 11.25 m/s = Easterly
component.

Y = 22.5*sin60 = 19.49 m/s = Northerly
component.
