(1) From an elevated position at 181 m over a horizontal terrain, at a region where the Acceleration of the Gravity is 7.15 m/s ² , a projectile is shot with an angle of 0° respect to the horizontal, and a velocity of 135 m/s . Determine: (a) horizontal displacement of projectile (b) its landing velocity (c) its landing angle.
Acceleration of Gravity g = 7.15 m/s ²
Cannon vertical position H = 181 m
Cannon elevation angle A = 0°
Shooting Velocity Vo = 135 m/s
(2) A projectile is shot with an elevation angle of 40°, a velocity of 120 m/s, in a place where the Acceleration of the Gravity is 9.00 m/s².
(a) Determine: the maximum height reached by the projectile, its ascending time, its flight time and its horizontal range.
(b) Get coordinates, velocities and the displacement vector angle with the x-axis, after 5.00 s of shooting.
(c) Find how long after shooting, the projectile is at 150.00 m height and get its position (x,y) and velocity (Vx,Vy) at that time.
