1. The radius of 4 hydraulic pistons are shown below. The two radii are those of the hose entering the piston adn the piston itself. The radius of each piston is identified on each. Rank these situations from greatest piston force to least piston force.
 
 

greatest _____________________ least or   ___ All equal or    _____ Can't be determined

 

2. Below is a diagram showing 4 sailboats. The letter "A" represents the area of each sail. The "m" represents the relative mass of each boat. The frictional force between the boat and the water is the same for each boat. Rank these situations from greatest acceleartion to the least acceleration.
 
 

greatest _____________________ least or   ___ All equal or    _____ Can't be determined
