#4 written values if not clear says 80m/s And 10s please clearly write simple step by step steps used to find answer

80 4. A projectile is shot from the edge of a cliff of unknown height at an initial velocity 45 m/s at an angle 30 above x axis. After s, the projectile lands on the ground at a distance, x away from the base of the cliff. [12] 105 I. Draw a diagram showing the projectile path starting from the edge of the cliff to the ground. Show launching velocity vector with their components and landing velocity vector with their components. II. determine the height of the cliff. III. determine the horizontal distance x, travelled by the projectile. IV. Determine the maximum height reached by the projectile. 5. Food supply is dropped from an airplane when the airplane was 230 m above the ground and was travelling at 156 km/h in the horizontal direction. [8] A. Draw the diagram of the projectile path of the supply starting from the point of release to the ground. B. Using downward direction positive y, and using kinematics equation, determine the time for the food supply to land on the ground and horizontal distance travelled during this time
