A ball is to be shot from level ground with a certain speed v0 at various angles θ. The launch angle determines both the time of flight t and the minimum speed vmin the ball will have during its flight, which means they can be related to each other. At some angle, the ball will have a maximum possible time of flight. Call this time tmax. Find a formula which gives the ratio of vmin to v0 in terms of t, tmax, and g.
I honestly do not know where to go with this one, it has stumped my roommate and i for over an hour!
It is asking for the answer in a ratio of vmin/v0
if simplified you can get an answer of vmin/v0 = v0 cos(theta)/v0 = cos(theta)
The computer does not accept this as a valid response.
Any help is appreciated,
Cheers!
