Problem requires the following to be answered: 1) Range, 2) total flight time and 3) max altitude. I need someone to review my range answer and my total flight time answer. In addition, I need some help setting up my max altitude.
The equation is (vcosθ)ti +[(vsinθ)t -1/2 gt^2]j
To get range, I set y=0 and solved for t.
y= (vsinθ)t -1/2 gt^2
0= (vsinθ)t -1/2 gt^2
1/2 gt^2 = (vsinθ)t
t= 2(vsinθ)/g TOTAL FLIGHT TIME
Inserted t into x= vcosθt
vcosθ * 2(vsinθ)/g
Need help on setting up max altitude
