About this 3D model

I have printed this cannon as teaching aid for teachers to explain the projectile motion. This woking model will develop interest of students. This will make it easier for students to understand the topic as its always easy to learn watching real working model. V0x = V0 cos(θ)V0y = V0 sin(θ) Ax = 0 and Ay = - g = - 9.8 m/s2 Vx = V0 cos(θ) Vy = V0 sin(θ) - g t x = V0 cos(θ) t y = V0 sin(θ) t - (1/2) g t2 Maximum Height = (V0sin(θ))2/2gHorizontal Range = V20sin(2θ)/g
