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

Solve problem #1 a, b, c and d in Newton's 2nd Law

1.3 kg hangs from the end of a (massless) string which runs
1) A block (block 2) of mass m2
over a (massless frictionless) pulley. The other end of the string is connected to another
block (block 1) of mass m, = 2.2 kg on a horizontal frictionless table. The situation is
shown below.

M,
a) Assuming that block 1 is sliding to the right (toward the pulley), find the acceleration of
block 1. (3.6 m/s²)
b) Assuming that block 1 is sliding to the right (toward the pulley), find the tension in the
string. (8.0 N)
c) Sarah repeats this experiment but she gives block 1 a push to the left, so now it is sliding
to the left (away from the pulley). Find the acceleration of block 1 (after Sarah has
stopped pushing it but while it is still sliding to the left). (3.6 m/s*)
d) As above in part c, block 1 is sliding to the left (away from the pulley). Find the tension
in the string (after Sarah has stopped pushing it). (8.0 N)
