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?

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

True or false: the revolution of the earth creates day and night as it rotates around the sun

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
