Questions and Answers

According to Newton's law of motion, what is the net force on an object with a mass of 5kg that is accelerating at a rate of 10m/s^2?

  • 10N
  • 50N (correct)
  • 500N
  • 5N
  • What happens to the acceleration of a 2 block system with friction when the mass of one of the blocks is increased?

  • The acceleration increases
  • The acceleration remains the same
  • The acceleration decreases (correct)
  • The acceleration becomes negative
  • What is the relationship between the coefficient of friction and the force of friction in a 2 block system with friction?

  • The force of friction is inversely proportional to the coefficient of friction
  • The force of friction is equal to the coefficient of friction
  • The force of friction is not affected by the coefficient of friction
  • The force of friction is directly proportional to the coefficient of friction (correct)
  • If a block with a mass of 10kg is placed on an inclined plane with an angle of 30 degrees and a coefficient of friction of 0.2, what is the force of friction acting on the block?
