Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

q4 and q5

Suppose you walk 21 m straight west and then 19 m straight north. How far are you from your starting point

1. Consider the physical quantities s, V, a, and t with dimensions [s] = L, [V] = L/T, and [a] = L/T?. Determine whether each of the
following equations is dimensionally consistent. (a) s = vt2 + 0.5at?; (b) v = s/t ; (C) a = v/t.
Enter your work below in the following manner; as outlined in the problem, use capital letters for units and lower case for
variables. So, (a) should look like this:
v2 = 2as
L2/T2 = [L/T2I[L]
L2/T2 = L2/T2 --> The equation is consistent.

I have a question for the square root of units. So I have the formula 2pi√m/k And m=50g and k=32,700 dynes/cm. (dynes is g x cm/sec2) So when I plug everything in and cancel units out im left with √654sec2 My question is does the square root cancel out with sec2 individually so i'll still have to square root 654 or does the square root cancel out with the whole thing and im left with 654 without having to square root it. Therefore leading to 2pi(654sec). Or would it be 2pi(25.6sec)
