A punter wants to kick a football so that the football has a total flight time of 4.70s and lands 57.0m away (measured along the ground). Neglect drag and the initial height of the football.
- How long does the football need to rise?
- What height will the football reach?
- With what speed does the punter need to kick the football? (vertical component, horizontal component, and vector magnitude)
- At what angle (θ), with the horizontal, does the punter need to kick the football?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
