Welcome to Math Help Forum!whereis the height above ground in metresYou won't be able to solve this completely (you haven't been given enough information) but you can get a set of possible solutions. Here's how:
is the time in seconds
takes values between and for all values of , so in the equation above, takes values from to . Therefore:This gives:
When . So plug these values into the equation using the values of and that we've just found:So the equation is of the form
, for any integer (This is using degrees - but you can write in radians if you like)
The only other option would be to eliminate , and express this in terms of and . Without more information, that's all you can say.
