(a) To determine The horizontal distance from the desired landing spot. Explanation The horizontal and vertical component are independent. At the moment the delivery drone landing at customer’s porch, only the vertical motion exists. Write the expression for vertical displacement. y = y 0 + v y 0 t − 1 2 g t 2 (I) Here, y is the vertical displacement, y 0 is the initial vertical displacement, v y 0 is the initial vertical velocity, t is the time, and g is the acceleration due to gravity. Write the expression for horizontal distance. x = v x o t (II) Here, v x 0 is the horizontal initial distance. Conclusion: Substitute, 0 for y 0 , v y 0 , 9.8 m / s 2 for g , 8.65 m for y in the equation (I), and solve for t . 8.65 m = 0 + 0 × t − 1 2 ( 9.8 m / s 2 ) t 2 t = 2 × 8 (b) To determine The speed at which the package hit the porch.
