Question

Suppose the departure angle in Figure 3.26 in the textbook is α0 = 41.0 ∘ and the distance is d = 2.90 m .

Dashed arrows show how far the dart and monkey have fallen at specific times relative to where they would be without gravity. At any time, they have fallen by the same amount. Without gravity The monkey remains in its initial position . The dart travels straight to the monkey. Therefore, the dart hits the monkey. Monkey's fall Dart's Trajectory of dart without gravity d tan An : fall Dart's fall 「Dart's fall. _-T-- Trajectory of dart with gravity With gravity The monkey falls straight down. At any time t, the dart has fallen by the same amount as the monkey relative to where either would be in the absence of gravity. Δydar-Aymonkey gt . Therefore, the dart always hits the monkey

a) Where will the dart and monkey meet if the initial speed of the dart is 12.4 m/s?

b) Where will the dart and monkey meet if the initial speed of the dart is 8.6 m/s?

c) What will happen if the initial speed of the dart is 4.0 m/s?
