Question

A monkey on a coconut tree throws a coconut horizontally from a height of 13 m. The coconut lands 5.0 m from the tree. With what velocity was the coconut thrown?

Answer 1

Answer:

3.1 m/s

Explanation:

x = vt cos∝ , y = vtsin∝ - gt²/2 , the coconut thrown horizontally ∝ = 0

x = vt  , y =  - gt²/2 = -13 , t = √26/g

v = x/t = 5 √(g/26) = 5 √10/26 = 3.1 m/s
