To find the time it takes for the ball to reach the given height, we need an equation that relates the height and time it travel which is given to be <span>h=-16t^{2}+56t. We just substitute the height of 49 feet then solve for t. We do as follows:
</span><span>h=-16t^{2}+56t
49 = </span>-16t^{2}+56t
t = 1.75 seconds
Hope this answers the question. Have a nice day.
Answer:
