2. The following formula relates three quantities: Force (F), mass (m), and acceleration (a).
F = ma
(a) Solve this equation for a.
(b) Let the force be units and the mass be m = 10 units. What is the acceleration, a?
(c) Let the force be F = 25 units and the acceleration be a = 5 units. What is the mass, m?

Respuesta :

growl
(A): Divide each side by m and you will get [tex] \frac{F}{m} = a [/tex]

(B): (You didn't tell me the units of force, so I can't give you the answer)

(C): m =

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

[tex] F=ma [/tex]

Part a) Solve this equation for a

[tex] F=ma [/tex]

Divide both sides by the mass

[tex] a=\frac{F}{m}[/tex]

therefore

the answer part a) is equal to

[tex] a=\frac{F}{m}[/tex]

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

[tex] a=\frac{F}{m}[/tex]

in this problem

we have

[tex] F=25\\m=10[/tex]

Substitute the values n the formula

[tex] a=\frac{25}{10}[/tex]

[tex] a=2.5[/tex]

therefore

the answer part b( is equal to

[tex] a=2.5[/tex]

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

we know that

[tex] F=ma [/tex]

Solve for m

Divide both sides by the acceleration

[tex] m=\frac{F}{a}[/tex]

in this problem

we have

[tex] F=25\\a=5[/tex]

Substitute the values n the formula

[tex] m=\frac{25}{5}[/tex]

[tex] m=5[/tex]

therefore

the answer Part c) is

[tex] m=5[/tex]
