In the figure, a horse pulls a barge along a canal by means of a rope. The force on the barge from the rope has a magnitude of $$7690\mathrm{N}$$ and is at the angle $$?=13.0^{?}$$ from the barge's motion, which is in the positive direction of an $$x$$-axis extending along the canal. The mass of the barge is $$9500\mathrm{kg}$$, and the magnitude of its acceleration is $$0.120\mathrm{m}/{\mathrm{s}}^2$$. What are (a) the magnitude and (b) the direction (measured from the positive direction of the $$x$$-axis) of the force on the barge from the water? Give your answer for (b) in the range of $$\left(?180^{?},180^{?}\right]$$ In the figure, you throw a ball toward a wall at speed $$39.0\mathrm{m}/\mathrm{s}$$ and at angle $${?}_0=42.0^{?}$$ above the horizontal. The wall is distance $$d$$ $$=23.0\mathrm{m}$$ from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall? (a) Number Unit (b) Number Unit (c) Number Unit
