Okay so I'm in grade 11 and I have this math question that I dont know how to do.
On planet claire the height, h metres, of an object is fired uprwards from the ground at 48 m/s is described by h=48t-16t^2 where t seconds is the time since object was fired upwards. Determine the maximum height of the object, the times at which the object is 32m above the ground, and the time it hits the ground.
Any help would be greatly appreciated.. Thanks a lot.
