Answer:A cylinder is a simple geometric shape with two equally-sized and parallel circular bases. Calculating the volume of a cylinder is simple once you know the formula.
Step-by-step explanation:
we are given
where
d is the horizontal distance the ball traveled in yards
f(d) is the height, in yards of the ball at d horizontal yards
Initial height:
For finding initial height , we can plug d=0
So, initial height is 0.8 yard
Initial Velocity:
We can find derivative
now, we can plug d=0
so, initial velocity is 5.4 yard vertically / yard horizontally
Hence , option-B.......Answer
