the height of an arrow shot into the air can be represented by the function h(t)= -16t2+112t+5 where t is the time in secounds since the arrow was shot. what is the maximum height of the arrow?
Thank you for the opportunity to help you with your question!
maximum height is reached when dh/dt=0
max height= -16(3.5^2)+112(3.5)+5= -196+392+5
maximum height is 201 m
