Answer:
0.594 m/s
Explanation:
First, find the time it takes to land.
Given, in the y direction:
Δy = 2.225 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(2.225 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.674 s
Next, find the horizontal velocity.
Given, in the x direction:
Δx = 0.400 m
a = 0 m/s²
t = 0.674 s
Find: v₀
Δx = v₀ t + ½ at²
(0.400 m) = v₀ (0.674 s) + ½ (0 m/s²) (0.674 s)²
v₀ = 0.594 m/s
More force needs to be applied

Answer:
22785 square inches
Explanation:
- As the mass of the tube is 30kg, therefore it is exerting a force of 30g N(30g = 30 × 9.8 = 294)
- So the force is 294 N.
- Pressure is 20 N/m², as given.
- As we know Pressure is equal to the force exerted per unit area (P=F/A).
A = 294 ÷ 20 = 14.7 m²
- As 1 m² = 1550 square inches. Therefore, 14.7 m² = 14.7 × 1550 square inches = 22785 square inches
