For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 28 N acts on
a certain
object, the acceleration of the object is 7 m/s². If the acceleration of the object becomes 3 m/s2, what is the force?
1 answer:
Answer:
Step-by-step explanation:
F=ma
28=7m
m=28/7=4
F=4a
when a=3 m/s²
F=4×3=12 N

A graph shows the roots to be
{-4, 3, 6}.
x = 2
Step-by-step explanation:
3(x + 1) - 2 = x + 5
3x + 3 - 2 = x + 5
3x + 1 = x + 5
3x - x = 5 - 1
2x = 4
x = 4 / 2
x = 2
