Every once in a while a bird will get hit by a baseball during a baseball game. The longest home runs in baseball land about 500 feet (which is 152.4 meters) from home plate. If these balls leave the bat at a 45 degree angle to maximize their distance, what is the minimum safe height in meters for birds around baseball stadiums?

I dunno if that is right.

I don't know Physics. Can anyone help @abc9837?

- anonymous

or it would be h (max) the top point of projectile

- anonymous

what u all think about this!!..

- anonymous

can u xplain what the hell this
"Every once in a while a bird will get hit by a baseball during a baseball game"
mean

- ParthKohli

It means exactly what it says.

@mathslover

actually this question does not seemt oo much hard to me. What we are given with is horizontal range (R) and theta (angle)
given : R = 500 ft. and theta = 45 degrees
Since \(R = \large{\frac{u^2 \sin 2\theta}{2g}}\) = 500ft.
put theta = 45 degrees and g = 10 m/s^2 . calculate the *u* first (initial velocity)

- mathslover

Oh sorry : R = \(\large{\frac{u^2 \sin 2\theta}{g}}\)

- ParthKohli

OK, we are assuming \(g = 9.8 ~m/s^2\)

- ParthKohli

No, \(9.81\)

- mathslover

ok

- nincompoop

|dw:1361877650810:dw|

- ParthKohli

\[500 = \dfrac{u^2 }{9.81}\]

- ParthKohli

\[u = \sqrt{500 \cdot 9.81}\]

- mathslover

that will come approx. u = 50 root 2 or 70.7 [ i took g = 10 m/s^2 ]

- mathslover

and if we take g = 9.81 then it is u = 70.03 m/s

- nincompoop

I think you two are making this way more complicated

- Opcode

Answer is zero.

- mathslover

now we have u as initial velocity
calculate the max. height of the projection (H):
\[\large{ H = \frac{ u^2 \sin ^2 \theta}{2g}}\]
Calculate H now.

- mathslover

I get it as 125 ft. (aprox.)

- mathslover

and exactly it is 124.9

- nincompoop

one unit is in meter and the other is in ft
can you reconcile this?

- ParthKohli

38.069 meters

- anonymous

oh fishy
what else i wrote in my first reply man!!!
@parthkohli

- mathslover

Yeah @rajshikhargupta you're also right . I think he might have not given view on that. Though , good to see you knew that :)

- agent0smith

I don't remember how I got here, but that is an awesome drawing by @nincompoop and it deserved more attention and medals.
Also, even though it's 2 months old, looks like you guys messed up your calculation @mathslover and @ParthKohli
"given : R = 500 ft.
put theta = 45 degrees and g = 10 m/s^2 "
You both used the range in feet, but gravity in metres...

- agent0smith

but, seriously,

lulz

hey now...

\[R=\frac{ Vo ^{2}\sin 2\theta }{ g }\]
\[Vo ^{2}=\frac{ Rg }{ \sin 2\theta }\]=\[[152.4m(9.81s ^{2}/m)]/[\sin(2*45)]\]=\[1495.044 s ^{2}\]
\[H=\frac{Vo ^{2} \sin ^{2}θ }{ 2g }\]
=\[\frac{ {(1495.044 s ^{2})[\sin(45)^{2}]} }{2*9.81 \frac{ m }{ s ^{2} } }\]
=38.1 m <------- answer
