kow [346]

Answer:

Distance S = 11.77 m (Approx.)

Explanation:

Given:

Time t = 1.55 Second

Gravity acceleration = 9.8 m/s²

Find:

Distance S

Computation:

S = ut + (1/2)(g)(t)²

S = (0)(1.55) + (1/2)(9.8)(1.55)²

S = (0)(1.55) + (1/2)(9.8)(1.55)²

Distance S = 11.77 m (Approx.)

Answer:

<h2>S.A. = 402.62 m²</h2>

Step-by-step explanation:

We have:

two right triangles with legs 4m and 6m

The area:

A_1=\dfrac{1}{2}(4)(6)=12\ m^2

three rectangles

22m × 6m

The area:

A_2=22\cdot6=132\ m^2

22m × 7.21m

The area:

A_3=22\cdot7.21=158.62\ m^2

22m × 4m

The area:

A_4=22\cdot4=88\ m^2

The Surface Area:

S.A.=2A_1+A_2+A_3+A_4

Substitute:

S.A.=2(12)+132+158.62+88=402.62\ m^2
