Quickly for 5 stars and 1. omar set off a rocket in a field. the height h of the rocket in feet can be roughly estimated using the formula h = -16t^2 + 128t, where t is the time in seconds. how long will it take the rocket to reach a height of 240 feet? 2. josefina tosses a ball upward with an initial velocity of 76 feet per second. she tosses it from an initial height of 2 feet. find the approximate time that the ball hits the ground. use the function h(t) = -16t^2 + 76t + 2 round to the nearest second. 3. brandi, an amateur skier, begins on the "bunny hill," which has a vertical drop of 200 feet. her speed at the bottom of the hill is given by the equation v^2 = 64h, where the velocity v is in feet per second and the height h of the hill is in feet. assuming there is no friction, approximate brandi's velocity at the bottom of the hill.
