- An object is launched from a platform. The path of the object can be modelled by the equation h = -ť? + 5t + 10, where t, in seconds, is the time from the launch and h, in metres, is the height of the object from the ground. Find the difference in height between the object at its highest point and at the point from which it was thrown.
