Answer:
The ladder can reach a height of 22.6 feet.
Step-by-step explanation:
In order to find the height that the ladder can reach, you need to use the Pythagorean Theorem. The Pythagorean Theorem assumes that the house to the ground will form a right triangle and the leaning ladder is the hypotenuse. Using the formula: a² + b² = c², we can plug in the values that we know and solve for the missing variable. In this case we know the base of the triangle 'b' and the hypotenuse 'c': a² + 8² = 24² or a² + 64 = 576. To solve for a, we must first subtract 64 from both sides: a² + 64 - 64 = 576 - 64 or a² = 512. In order to find just the value of 'a', which represents the height, we need to take the square root of both sides: √a² = √512 or a ≈ 22.6 feet.
For this case what we should do is use the given equation:
F = mg sin (theta)
And replace the following values:
m = 0.01 kg
g = 9.8m / s ^ 2
theta = 22.5 degrees
Substituting we have:
F = (0.01) * (9.8) * sin (22.5)
F = 0.037502976 N
Answer:
The force pulling on the pendulum when it makes a 22.5 degree angle with the vertical is:
F = 0.037502976 N
Answer: They can buy 16 coats.
Step-by-step explanation:
All you have to do is divide $740 by $46.25 and you will get 16 which will be your final answer.
