Question 917284: how many seconds after it was shot will the charge first be 2000 feet high?
how many seconds after it was shot will be charge next be 2000 feet high?
the equation is -16t^2 +1000t+50

h= -16t^2+1000 t+50
if h= 2000 ft
then 2000 = -16t^2+1000t +50

hence after 2 seconds or 60 seconds it will reach 2000 ft ------statement1
when h =2000 ft+2000 ft ( further 2000 ft)
4000 =-16t^2+1000t +50
