Aball is launched directly in the air at a speed of 40 feet per second from a platform located 10 feet in the air. the motion of the ball can be modeled using the function f(t)=−16t2+40t+10, where t is the time in seconds and f(t) is the height of the ball. when, in seconds, will the ball hit the ground? write your answer to the nearest hundredth of a second. do not include units in your answer.
