1 a duck has a mass of 20 kg as the duck paddles a force of, Ask an Expert

Academics

1) A duck has a mass of 2.0 kg. As the duck paddles, a force of 0.06 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.16 N in a direction of 56° south of east. When these forces begin to act, the velocity of the duck is 0.13 m/s in a direction due east. Find the magnitude and direction (relative to due east) of the displacement that the duck undergoes in 2.1 s while the forces are acting.

2) A soccer player kicks the ball toward a goal that is 28.6 m in front of him. The ball leaves his foot at a speed of 19.1 m/s and an angle of 30.2° above the ground. Find the speed of the ball when the goalie catches it in front of the net. (Note: The answer is not 19.1 m/s.)
