Answer:
6.1 m/s
Explanation:
Take up to be positive. Given (in the y direction):
Δy = 1.4 m
vᵧ = 0 m/s
g = -10 m/s²
Find: v₀ᵧ
vᵧ² = v₀ᵧ² + 2aΔy
(0 m/s)² = v₀ᵧ² + 2 (-10 m/s²) (1.4 m)
v₀ᵧ = 5.29 m/s
The vertical component is 5.29 m/s. So the total magnitude of the initial velocity is:
v₀ᵧ = v₀ sin θ
5.29 m/s = v₀ sin 60°
v₀ = 6.11 m/s
Rounding to two significant figures, the fish must spit the water at 6.1 m/s.
