I am solving some problems of my physics book for fun and for some reason I am getting a wrong answer from this one. 1. The problem statement, all variables and given/known data A bullet is shot at an angle of 35o with a speed of 90 m/s. I assume that air resistance is ignored. Calculate bullet's distance from launch site 2,5 seconds after the shot. 2. Relevant equations x = vox * t vox = vo * cosθ 3. The attempt at a solution The horizontal speed should stay as it is. vo = 90 m/s t = 2,5 s θ = 35o x = vox * t = vo * cosθ * t = 90 m/s * cos 35o * 2,5 s = 184,309... m ≈ 184 m The book says that the answer should be 210 m. I cannot think of any other way to solve this.
