a force is applied to the right to drag a sled to the right across Loosely packed snow with a rightward acceleration (considered friction forces)​

1.67 m/s²

Explanation:

Total force is;

ΣF = F_f + F_a

From the free body diagram attached, we see that the frictional force F_f is acting in a negative direction.

Thus;

ΣF = -15 + 30

ΣF = 15 N

Now, to get the acceleration, we will use the formula;

ΣF = ma

We are given m = 9 kg

Thus;

15 = 9a

a = 15/9

a = 1.67 m/s²

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

like poles repel so keep pushing north to north and repels funny to see this
