1. The problem statement, all variables and given/known data A cannonball is fired with a velocity of 125 m/s at 25.0° above the horizontal a) Determine the horizontal and vertical components of the initial velocity. b) Determine the maximum height the cannonball reaches in its path c) Determine the time it takes to reach maximum height. d) Determine the hang time of the cannonball. e) Determine the range of the cannonball. f) Draw a sketch of the motion of the projectile including the horizontal and vertical components of velocity when the projectile strikes the ground. Draw the appropriate relative lengths of the vectors for these components. 2. Relevant equations a) V1x = v1 (cos), V1y = v1 (sin) b) v2^2 = v1 + 2ad c) D= (0.5)(V1 + V2)(t) d) t = (v2- v1)/a e) dx = (V1x)(t) f) unknown 3. The attempt at a solution a) V1x = (125 m/s)(cos 25) = 113.3 m/s right V1y = (125 m/s)(sin 25) = 52.8 m/s up b) (0m/s)^2 - (52.8m/s)^2/ (2 x -9.80 m/s2) = 142.4 m c) 142.2 = (0.5)(52.8 m/s +0 m/s)(t) 142.2 = 26.4 x t T = 5.4 s d) T = [0 m/s)-(125 m/s)]/ -9.8m/s^2 = 12.76 12.76 x 2= 25.52 s (“Hang time” refers to the length of time that a projectile is in the air.) e) dx = (113.3 m/s)(25.52s) = 2.89 x 10^4m f) If I know which equation I should use for this one, I will appreciate it.
