Homework Statement
In the Fig.
What should be the initial velocity (magnitude and direction) of the arrow? Also calculate the time of flight.
Homework Equations
The Attempt at a Solution
I have formulated 2 equations:
v*cos(theta) * t = 20
and 3 = (v * Sin(theta) * t) + (9.81 * t^2)/2
when t = time of flight
and v = initial velocity
I have further gone to a final equation
v = (2000+2000(tan(theta))^2)/ (3 + 20 Tan(theta))
Any help please.
