Your annoying little brother is dropping rocks out of his bedroom window on the 2nd floor. You are on the ground floor and watch

a rock fall past the patio door onto the ground below. In this problem, ignore air resistance. If the rock takes 0.28 s to cross the 2.3-m-high glass door, from what height above the top of the door was it dropped?

Multiply the number 4.48E-8 by 5.2E-4 using Google. What is the correct answer in scientific notation?
Ostrovityanka [3204]

Answer:

2.32\times 10^{-11}

Explanation:

The first number is 4.48\times 10^{-8}.

The second number is 5.2\times 10^{-4}.

We must multiply these two numbers together.

4.48\times 10^{-8}\times 5.2\times 10^{-4}=(4.48\times 5.2)\times 10^{(-8-4)}\\\\=23.296\times 10^{-12}

In scientific notation: 2.32\times 10^{-11}

Therefore, this is the solution you are looking for.

To see if your results are reasonable, you can compare the final velocity of the stone as it falls down unwinding the wire from
Sav [3153]

Response:

The stone's velocity is 2.57 m/s.

Clarification:

Provided that

Height = 0.337 m

We need to determine the velocity of the stone

Using the motion equation

v^2-u^2=2gh

Where, v = velocity of the stone

u = initial velocity

g = gravity's acceleration

h = height

Substituting into the formula

v^2-0=2\times9.8\times 0.337

v=\sqrt{2\times9.8\times0.337}

v=2.57\ m/s

Thus, the stone's velocity is 2.57 m/s.
