Predict/Calculate Beating to Windward A sailboat can be propelled into the wind by a maneuver called beating to windward. Beating requires the sailboat to travel in a zigzag pattern at an angle to the wind that is greater than the no-go zone, which is shaded red in Figure 7-23. When a sailboat is just outside the no-go zone (boats B in the figure) the wind exerts a force
F = 870 N
and
v = 11 m/s,
what propulsion power is delivered to sailboats B, for which
θ = 79°
? (c) What propulsion power is delivered to sailboats C for which
θ = 56°
?

- A cart is set rolling across a level table, at the same speed on every trial. If it runs into a patch of sand, the cart exerts on the sand an average horizontal force of 6 N and travels a distance of 6 cm through the sand as it comes to a stop. It instead the cart runs into a patch of gravel on which the can exerts an average horizontal force of 9 N, how far into the gravel will the cart roll before stopping? (a) 9 cm (b) 6 cm (c) 4 cm (d) 3 cm (e) none of those answersarrow_forwardA 0.500-kg potato is fired at an angle of 80.0 above the horizontal from a PVC pipe used as a “potato gun” and reaches a height of 110.0 m. (a) Neglecting air resistance, calculate the potato’s velocity when it leaves the gun. (b) The gun itself is a tube 0.430 m long. Calculate the average acceleration of the potato in the tube as it goes from zero to the velocity found in (a). (c) What is the average force on the potato in the gun? Express your answer in newtons and as a ratio to the weight of the potato.arrow_forwardThe masses of the javelin, discus, and shot are 0.80 kg, 2.0 kg, and 7.2 kg, respectively, and record throws in the corresponding track events are about 98 m, 74 m, and 23 m, respectively. Neglecting air resistance, (a) calculate the minimum initial kinetic energies that would produce these throws, and (b) estimate the average force exerted on each object during the throw, assuming the force acts over a distance of 2.0 m. (c) Do your results suggest that air resistance is an important factor?arrow_forward
- A 44.0-kg child finds himself trapped on the surface of a frozen lake, 10.0 m from the shore. The child slips with each step on the frictionless ice and remains the same distance from the shoreline. Egged on by his parents, he throws a 0.750-kg ball he is carrying toward the center of the lake with a horizontal speed of 1.50 m/s, in the direction opposite that of the shoreline. a. Does the act of throwing the ball cause the child to move? If so, what are the speed and the direction of his motion with respect to the Earth? b. What are the forces acting on the child when he throws the ball?arrow_forwardA 40kg girl gets on a 10kg wagon at ground level with two 5 kg bricks.

(A) Find the speed of the block after it has moved 4 m if the surfaces in contact have a coefficient of kinetic frietion of 0.15 as shown in Figure (a). (B) Suppose the force F is applied at an angle 6 as shown in Figure (b). At what angle should the force be applied to achieve the largest possible kinetic energy? F F (a) (b)arrow_forward
- How do I do this?arrow_forwardA volleyball player starts a serve by throwing the ball vertically upward. The 240g volleyball comes to rest at its maximum height. The server then hits it and exerts an average horizontal force of magnitude 6.2 N on the ball. Determine the speed of the ball after the player hits it if the average force is exerted on the ball for 600 ms.arrow_forwardV h | "1470-24 g plates A particle of mass m is moving along the +x-axis with constant speed vo. At time t = 0 it enters a region between two plates which are separated by a distance h and lie in the x - z plane as shown in the figure. The figure is a side view of the plates with the +z axis pointing out of the screen. After entering the region between the plates, the particle is acted on by both gravity (which points in the -y direction and has magnitude g) and by a time varying force that points upward, in the +y direction, with magnitude F = bt, where b is a positive constant and is large enough that the particle does not touch the bottom plate. 1. Sketch the trajectory of the particle. 2. How long does it take for the particle to reach its lowest point? 3. If the particle is initially at the midpoint between the two plates, what is the minimum possible value of b such that the particle does not hit the lower plate? 4arrow_forward
