The force (y) applied on a body of constant mass id directly proportional to the acceleration (x) done by the body, express this in the form of equation is two variables. Find the expression and the value of force (y), when acceleration (x) is 2 units.

Answer 1

recall that F = ma
using your variables, y = mx

Answer 2

From F = ma:
F = y,
a = x

New equation: y = mx
Since acceleration (x) = 2,
Force (y) = 2m
