**Physics please help**

A duck has a mass of 2.8 kg. As the duck paddles, a force of 0.05 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.15 N in a direction of 60° south of east. When these forces begin to act, the velocity of the duck is 0.12 m/s in a...

**Physics please help!!**

loss of potential energy = m g (18-9) so mg(18-9) = (1/2) m v^2 + loss due to friction or 30(9.8)(9) = 15(9.3)^2 + loss due to friction
