Suppose that two carts, one twice as massive as the other, fly apart when the compressed spring that joins them is released. What is the acceleration of the heavier cart relative to that of the lighter cart as they start to move apart?

Solution 23E Introduction According to Newton’s 3rd law of motion, for every action, there is an equal and opposite reaction. According to Newton’s 2nd law of motion, the rate of change of momentum is directly proportional force applied. Therefore, force, = ma Where, m - mass of the body a - acceleration Step 1 Consider, the system is at rest initially. Hence the forces are balanced on each cart. So, consider the force of cart with mass “m” is F. The force, F = ma. Where, ‘a’ is the acceleration of the cart. Since the system is at rest, the force...
