1) At a skating rink a dresser that has a mass of 100kg is sitting on the ice. Solve the force of friction that would resist a group of children pushing the dresser off of the ice.
2) A slab of concrete sitting on the floor has a mass of 189kg. Calculate the friction force that would resist movement if the coefficient of static friction was 0.39
3) A slab of concrete with a mass of 93kg requires a force of over 919N in order to make it move. Calculate the coefficient of friction in this situation.
4) A sofa with a mass of 114kg requires a force of over 532N in order to make it move. Calculate the coefficient of friction in this situation.
5) A table with a mass of 122kg requires a force of over 424N in order to make it move. Determine the coefficient of friction in this situation.
6) Calculate the type of friction involved in the following situation.
A slab of concrete with a mass of 196kg is sitting motionless on a surface when someone decides to push it.
7) Solve the type of friction involved in the following situation.
A sofa is resting on a ramp and then the angle is slowly increased until until the sofa starts to slide.
8) Solve the type of friction involved in the following situation.
A bookshelf with a mass of 226kg is sliding across a surface and slowly coasting to a stop.
9) Determine the type of friction involved in the following situation.
Helen is pushing a block of wood across a floor at a constant velocity of 3.6m/s.
10) Solve whether a 227kg sofa sitting on a surface with a coefficient of static friction of 0.58 would move if a force of 634N were applied. If so, solve the net force.
