Hi there!

Recall the equation for momentum:

\large\boxed{p = mv}\\

p = momentum (kgm/s)

m = mass (kg)

v = velocity (m/s)

We can plug in the given values to solve for velocity:

-450 = 35v\\\\v = \frac{-450}{35} = \boxed{12.86 m/s}

A flat roof is very susceptible to wind damage during a thunderstorm and/or tornado. If a flat roof has an area of 500 m2 and wi
Evgesh-ka [11]

Answer: The magnitude of the force exerted on the roof is 490522.5 N.

Explanation:

The given data is as follows.

Below the roof, v_{1} = 0 m/s

At top of the roof, v_{2} = 39 m/s

We assume that P_{1} is the pressure at lower surface of the roof and P_{2} be the pressure at upper surface of the roof.

Now, according to Bernoulli's theorem,

P_{1} + 0.5 \times \rho \times v^{2}_{1} = P_{2} \times 0.5 \rho \times v^{2}_{2}

P_{1} - P_{2} = 0.5 \times \rho \times (v^{2}_{2} - v^{2}_{1})

             = 0.5 \times 1.29 \times [(39)^{2} - (0)^{2}]

             = 0.645 \times 1521

             = 981.045 Pa

Formula for net upward force of air exerted on the roof is as follows.

          F = (P_{1} - P_{2})A

             = 981.045 \times 500

             = 490522.5 N

Therefore, we can conclude that the magnitude of the force exerted on the roof is 490522.5 N.
