Question

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 F = -25 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?

Answer 1

b. -2.5
c. 5
F=ma
M=f/a
A=f/m

Answer 2

Answer:

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

a= 2.5 units

m= 5 units

Step-by-step explanation:

Force (F), mass (m), and acceleration (a).

F = ma

(a) solve for 'a'. we need to get 'a' alone

$F = ma$

Divide both sides by m

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

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

(b) let the force be F = -25 units and the mass be m = 10 units.

We replace the value in the equation we got in part 'a'

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

$a=\frac{-25}{10}=-2.5$

Acceleration a=-2.5

(c) let the force be F = 25 units and the acceleration be a = 5 units

$F = ma$

$25 = m5$

Divide both sides by 5

m= 5 units
