2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).

castortr0y [4]

Let

F--------> represent the force

m--------> represent the mass

a-------> represent the acceleration

we know that

The formula that relates three quantities: Force (F), mass (m), and acceleration (a) is equal to

$F=ma$

Part a) Solve this equation for a

$F=ma$

Divide both sides by the mass

$a=\frac{F}{m}$

therefore

the answer part a) is equal to

$a=\frac{F}{m}$

Part b) Let the force be 25 units and the mass be m = 10 units. What is the acceleration, a?

we know that

the formula of acceleration is equal to

$a=\frac{F}{m}$

in this problem

we have

$F=25\\m=10$

Substitute the values n the formula

$a=\frac{25}{10}$

$a=2.5$

therefore

the answer part b( is equal to

$a=2.5$

Part c) Let the force be F = 25 units and the acceleration be a = 5 units. What is the mass, m?

we know that

$F=ma$

Solve for m

Divide both sides by the acceleration

$m=\frac{F}{a}$

in this problem

we have

$F=25\\a=5$

Substitute the values n the formula

$m=\frac{25}{5}$

$m=5$

therefore

the answer Part c) is

$m=5$

Sabrina rode on a Ferris wheel at the state fair. The radius of the Ferris wheel was 106 feet. What is the approximate distance

Setler [38]

9514 1404 393

Answer:

666 ft

Step-by-step explanation:

The circumference of the wheel is given by the formula ...

C = 2πr

For a radius of 106 ft, the circumference is ...

C = 2(3.14)(106 ft) = 665.68 ft

Sabrina traveled about 666 feet in one revolution.

Last week, there were 450 student absences at Johnson High. The circle graph below summarizes them by the day of the week on whi

Rus_ich [418]

Answer:

Percentage of absentees on Tuesday = 16%

Step-by-step explanation:

Sum of all central angles representing days = 360°

Central angle of the sector representing Tuesday = 57.6°

Therefore, percentage absentees on Tuesday

= $\frac{\text{Measure of central angle for Tuesday}}{\text{Sum of all central angles}}\times 100$

= $\frac{57.6}{360}\times 100$

= 16%

Percentage of absentees on Tuesday = 16%
