Question

1) A guy stands a frinctionless skate board andpushes the wall with a force of 20 N. How hard does the wall push back on him? If his mass is 100 kg, what is the magnitude of heracceleration? Is it towad the wall or away from the wall? 2) If you push on a crate with a force of 100 N and it slidesat a constant velocity, what is the magnitude of the frictionacting on the crate? Thanks SO MUCH!! =) 1) A guy stands a frinctionless skate board andpushes the wall with a force of 20 N. How hard does the wall push back on him?
