A football was kicked vertically upward from a height of 4 feet with an initial speed of 60 feet per second. The formula $$h=4+60 t-16 t^{2}$$ describes the ball's height above the ground, $h$, in feet, $t$ seconds after it was kicked. Use this formula to solve. What was the ball's height 2 seconds after it was kicked?

Soccer Ball Kick The height h(t), in meters, above the ground of a certain soccer ball kick t seconds after the ball is kicked can be approximated by h(t)=-4.9(t square) + 12.8t. Determine the time for which the ball is in the air. Round to the nearest tenth of a second.
