Abel challenges kato to use the equation for the time for any projectile to reach maximum height in the absence of air resistance, given by ty, max = vi sin θi g , and the kinematic equation yf = yi + vi(sin θi)t − 1 2 gt2, to determine the maximum height, h, of the tennis ball, given the initial launch angle and speed. which of kato's attempts is correct?

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?
