For a moving object, the force acting on the object varies directly with the objects acceleration. When a force of 45 N acts on a certain object, the acceleration of the object is 9 m/s2. If the force is changed to 20 N, what will be the acceleration of the object.

is there more to this question?

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
