Question

when a baseball is hit by a batter the hight of ball,h (t)at time t,is determined by the equation h (t)= -16t^2+64t+4.for which interval of time is the height of the ball grater than or equal to 52 feet?​

Answer 1

If we differentiate the given equation,

We find that the differentiation of the given equation is -36t+64,

Now height is 52,

equating,

52=-36t+64

52-64=-36t

-12=-36t

then t= 12/36 = 1/3 secs.
