1) The height of a baseball hit 1 meter off the ground at an initial velocity of 40 meters is given by h(t) = - 4.9t2 + Vo t + So. Write the equation for the motion of the object. What is the maximum height in meters, that the ball will reach? After how many seconds will the ball reach its maximum height? How long does it take the ball to hit the ground?

help!!!

anonymous · Answer

max is at the vertex

anonymous · Answer

$$ h(t) = - 4.9t^2 + V_0t + S_0$$

anonymous · Answer

you know what $S_0$ and $V_0$ are? they are given to you in the question

anonymous · Answer

$V_0$ is the initial velocity , and you are told " initial velocity of 40 "

anonymous · Answer

$S_0$ is the initial height, and you are given "The height of a baseball hit 1 meter "

anonymous · Answer

therefore 
$$h(t)=-4.9t^2+40t+1$$

anonymous · Answer

how can u foil it tho?

anonymous · Answer

do u need to do that to find how long it takes for the ball to hit the ground?
