The height h (in feet) of an object after it is launched given by the function h = -16t^2 + v0t+h0 where v0 is the initial vertical vole city, h0 is the initial height of the object, and t is the time (in seconds) after the object is launched . A toy rocket is launched from the ground level with an initial vertical velocity of 96 ft/s. After how many se done will the rocket hit the ground ?

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
