A ball is tossed into the air from height of 8 feet with an initial velocity of 8 feet per second. find the time r(in seconds) i
t takes for the object to reach the ground by solving the equation -16t + 8t + 8 = 0 you trimmed a large strip of wallpaper from a scrap to fit into the corner of a wall you are wallpapering. you trimmed 15 inches from the length
For this case we have the following equation: -16t + 8t + 8 = 0 The first thing we must do is rewrite the equation correctly. We have then: -16t ^ 2 + 8t + 8 = 0 Solving the polynomial we have: t1 = -1/2 t2 = 1 We discard the negative root because we want to find the time. Answer: it takes for the object to reach the ground about: t = 1 second
