Newton's Second Law of Motion Quiz

What is the force required to produce an acceleration of 40 m/s² on a cricket ball with a mass of 0.5 kg?

• 30 N

• 20 N

• 10 N

• 40 N

According to Newton's second law, what is the formula to calculate force?

• F = a / m

• F = m * a

• F = m / a

• F = m + a

• 5 m/s²

• 4 m/s²

• 6 m/s²

• 7 m/s²

If a car has a mass of 1400 kg and is moving with an initial velocity of 10 m/s, what is the force required to stop it in 2 seconds?

• -8000 N

• -7000 N

• -6000 N

• -5000 N

What does a negative force indicate in the context of stopping a car?
