Homework Statement
A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.81 m directly above the back line, and the ball's initial velocity makes an angle theta = 48° with respect to the ground
find:
a.) vi the ball must be hit at to barely make it over the net
b.)the maximum height reached by the ball in this case
c.)vi for the ball to be hit so it directly lands on the opponent's back sideline
d.) the maximum height for the ball in this case
e.)maximum vi for the ball to barely make it over the net and just barely land in bounds
(for the contact point in previous problems, what is the maximum vi)
f.)if you hit the ball at this maximum vi, what angle should you hit it at?
Homework Equations
d=vt for the x direction
free fall equations for the y direction
The Attempt at a Solution
~i know the answer to a is 9.73 m/s what will i do with this in part b?
~for b. i would like to know how to set up this problem
correct any errors for this question please
dx=9.0m
vx= ?
t=9.0/vcos48
dy= 0.62m because it it hit i.81m above the ground
viy= ?
a=-9.8 m/s^2
~part c is basically like part a but dx is 18.0m and i believe your dy is 2.43
~i think part d is like part b
and i haven't tried part e or f so help will be of great appreciation! thanks to anyone who replies!
