A 0. 75-kg ball is attached to a 1. 0-m rope and whirled in a vertical circle. The rope will break when the tension exceeds 450

8090 [49]

At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is

∑ F = 450 N - (0.75 kg) g = (0.75 kg) a

where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of

a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²

Then its maximum tangential speed v is such that

a = v² / (1.0 m)

⇒ v = √((1.0 m) a) ≈ 25 m/s

The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journa

Misha Larkins [42]

The program is an illustration of a sequential structure

<h3>What are sequential control structures?</h3>

Sequential control structures are programs that do not require loops and conditional statements

<h3>The actual program</h3>

The program in Python where comments are used to explain each line, is as follows:

#This gets input for age

age = int(input("Age: "))

#This gets input for weight

weight = (input("Weight: "))

#This gets input for the heart rate

heartRate = float(input("Heart Rate: "))

#This gets input for the time

time = int(input("Time: "))

#This calculates the calories burnt

calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991 ) * time / 8.368

#This prints the calories burnt

print('calories: {:. 2f} calories'. Format(calories))

Identify the reference angle es001-1. Jpg for each given angle, es001-2. Jpg. Es001-3. Jpg degrees. Es002-1. Jpg degrees. Es003-

julia-pushkina [17]

The reference angle is the smallest angle between the terminal side and the x-axis.

$(1)\ \theta = 300^o$

300 degrees is in the 4th quadrant.

So, the reference angle is

$\alpha = 360 - \theta$

$\alpha = 360 - 300$

$\alpha = 60^o$

Hence, the reference angle of 300 degrees is 60 degrees

$(2)\ \theta = 225^o$

225 degrees is in the 3rd quadrant.

So, the reference angle is

$\alpha = \theta - 180$

$\alpha = 225 - 180$

$\alpha = 45^o$

Hence, the reference angle of 225 degrees is 45 degrees

$(3)\ \theta = 480^o$

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 120$

$\alpha = 60^o$

Hence, the reference angle of 480 degrees is 60 degrees

$(2)\ \theta = -210^o$

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 150$

$\alpha = 30^o$

Hence, the reference angle of -210 degrees is 30 degrees
