Newton's Third Law: Exercise 2

If a man stands next to a wall on a frictionless skateboard and push the wall with a force of 50 N,
Questions:
  1. How hard does the wall push on the man?
  2. If the man's mass is 70 kg, show that your acceleration is 0.71 m/s2.
  3. Answers:
    1. The wall reacts with a force oppsit to the man = − 50 N
    2. Having the mass m = 70 kg, acceleration a = F/m = 50 / 70 = 0.71 m/s2
