*PLEASE HELP*!!COIN IS TOSSED UPWARD FROM A BALCONY 188FT HIGH WITH AN INITIAL VELOCITY OF 32FT PER SEC. THE HEIGHT OF THE COIN, IN FT AFTER "T" SECONDS IS GIVEN BY FUNCTION h(t)=16^2+32+188. FOR WHAT LENGTH OF TIME WILL THE COIN BE AT THE HEIGHT OF AT LEAST 60 FT?

Best ResponseYou've already chosen the best response.0cuz right now with what you have... it would just be.... 476 no matter what... which is impossible

Best ResponseYou've already chosen the best response.0That's all the info i have. I have the answer which is 0 sec to 4 sec but not sure how they got that.

Best ResponseYou've already chosen the best response.0O.o.......i mean the equation would work better if it was lik \[h(t)=16(T^{2})+32T+188\]

Best ResponseYou've already chosen the best response.0that would make more sense... in which you would substitute h(t) for 60 and then solve from there

Best ResponseYou've already chosen the best response.0@mandonut ..... its not a max question... its asking for the position of the ball

Best ResponseYou've already chosen the best response.0so then it would be \[60=16(T^{2})+32T+188\]

Best ResponseYou've already chosen the best response.0pull the 60 over to get.... \[0=16(T^{2}) +32T +128\]

Best ResponseYou've already chosen the best response.0now you can take out 16 from the whole equation to get.... \[0=T^{2}+2T+8\]

Best ResponseYou've already chosen the best response.0of which can turnn into ..... \[0=(T+4)(T+2)\]

Best ResponseYou've already chosen the best response.0so then T={4,2} since you're dealing with only positive time (as time usually can only be positive)... you get T=4
