Question

y=f(t)=-16t^2+50t+34
a) how high above the ground is the bridge in feet?
b) What is the average velocity of the ball in for the first second?
c) Decide at what time, t, the ball reaches its maximum height. Round the answer to one decimal place.(in seconds)

anonymous · Answer

is y describing the position of the ball

anonymous · Answer

if it is.
for a, the height of the bridge will be the ball's position when t is 0

anonymous · Answer

yea y is the position of the ball

anonymous · Answer

for c) you can take the derivative of y and set that equal to zero to find the max position

anonymous · Answer

do those two answers make sense

anonymous · Answer

can you get b) by yourself
