a) Tetherball is a game that uses a ball hanging from a string attached to the top of a post, where the ball is sent flying around in the tangential direction. Assume a uniform gravitational acceleration g pointed downward. This is an example of what is known as a “conical pendulum.” i) Find the equilibrium angle that the string makes with the vertical for a given speed v such that the ball traces a circle at uniform height. ii) Estimate...

In the game of tetherball a rope with length L = 1.40 m connects a ball with mass m = 0.500 kg to the top of a vertical pole so that the ball can spin around the pole as shown in the figure. L 0 What is the speed v of the ball as it rotates around the pole when the angle 0 of the rope is 34.0° with the vertical? m U = 1.917 m/s Incorrect

As shown in the diagram below, a soccer player kicks a ball directly toward the goal along a displacement vector r, which has a length of 9.4 m and a direction 30 degrees east of south. Alternatively, she could have kicked it to a second player standing directly in front of the goal along a displacement ry, who could have then kicked it to the goal along a displacement vector rx as...

A ball of mass m is suspended from a string, and after being
given a push,moves along a horizontal circular path like the one
shown in the diagram.The length of the string is L and the angle
the string makes with the vertical axis is a constant θ. As you
watch the ball travel around it’s circular path you notice that the
ball is traveling with an unknown constant speed. The only forces
acting on the ball are the forces...

Please answer all in steps! while laying on the South Oval grass on a beautiful spring day, you notice two African swallows flying toward each other, both of them carrying coconuts. The first swallow is flying north horizontally with a speed of 20 m/s and the other swallow is flying south horizontally at the same height with a speed of 15 m/s. The mass of the first swallow is 0.27 kg and the mass of his coconut is 0.80 kg....
