1. The problem statement, all variables and given/known data Knowing that snow is discharged at an angle of 40 degrees, determine the initial speed, v_{0} of the snow at A. Answer: 6.98 m/s 2. Relevant equations 3. The attempt at a solution I have found the x and y velocity and position formulas. Now since I don't know time, should I solve both position equations for time (t) and set them equal to each other to get my only unknown, v_{i}? The quadratic equation for time in the y-dir seems a bit hectic. Is there an easier way to go about trying to find v_{i}?
Start with L = v_{0} t cosθ Δy = v_{0} t sinθ - (1/2) g t^{2} Solve the first equation for t and replace in second equation. Solve the ensuing equation for v_{0}.
I believe this is what you had in mind. The answer matches the professor's answer. Thanks again kuruman!
