Consider a 1-kg cart being pulled by a 10-N applied force. According to Newton’s second law, what is the acceleration of the cart? (use g = 10 m/s² for ease of calculations)

• 10 N

• 1 N

• 10 m/s²

• 1 m/s²

Consider the acceleration of the cart when the applied force is due to a 10-N iron weight attached to a string draped over a pulley. Will the cart accelerate as before, at 10 m/s2? The answer is no, because the mass being accelerated is the mass of the cart plus the mass of the piece of iron that pulls it. Both masses accelerate. The mass of the 10-N iron weight is 1 kg—so the total mass being accelerated (cart + iron) is 2 kg. What is the acceleration of the cart+iron system? (use g = 10 m/s² for ease of calculations)

• 0.2 m/s²

• 2 m/s²

• 5 m/s²

• 10 m/s²
