A golf ball is hit from the ground with an initial speed of 192 feet per second. Assume the starting height of the ball is 0 feet. How long will it take the golf ball to hit the ground?

Question

smored · Answer

you asked the exact same question like 10 mins ago

mikezack123 · Answer

@smored i never got help for it

smored · Answer

well, your other question will eventually be bumped to top if not answered, but you closed it.

richyw · Answer

what club did they use? This would depend on the angle they hit the ball at.

smored · Answer

that is true.

mikezack123 · Answer

@richyw @smored very funny

smored · Answer

what is the angle of elevation?

mikezack123 · Answer

It doesn't specify

richyw · Answer

well it's a valid question. I dunno any golfers who hit balls straight up, it would land back in the same spot! waste of a stroke.

richyw · Answer

but if we assume that this the vertical component of velocity, we can get an answer.

mikezack123 · Answer

yeah i think were supposed to assume it goes straight up

smored · Answer

the golfer could hit it parallel to the ground, and the time would be 0.

richyw · Answer

yeah, could be putting from very far away!

richyw · Answer

what equation do you want to use MikeZack?

mikezack123 · Answer

straight up

smored · Answer

btw, it is nearly impossible to his a golf ball vertically at that speed

richyw · Answer

No, I mean assuming it is going straight up, can you identify which kinematic equation you think will be easiest to use?

mikezack123 · Answer

@smored okay lets make a complaint to florida virtual school because their questions don't make sense

mikezack123 · Answer

@richyw what equations are the options?

richyw · Answer

you can do that. but do you want to figure it out with the assumption that it was hit straight up?

smored · Answer

why would i? it wont affect me and plus it doesnt say that you should assume that the golfer hits it perpendicular to the ground.

richyw · Answer

the kinematic equations. I will assume you have seen them?

mikezack123 · Answer

nope is that physics? I'm doing algebra

richyw · Answer

did they give you a function which describes height as a function of time? or airtime as a function of initial velocity?

mikezack123 · Answer

lets just assume the angle of it is 90

mikezack123 · Answer

you get 12 right?

mikezack123 · Answer

is the answer 12?

mikezack123 · Answer

fuuuck your kidding right?

richyw · Answer

I actually do get about that. I forgot what acceleration was in feet/s^2

richyw · Answer

so yeah you got it correct. not sure how if you don't know the equations... haha. anyways, good work.
