AP Physics Big Beautiful Bodacious Newton's Law Practice Test

     
    Assume magic land unless otherwise stated.
     
1 ) Martha pushes on a trunk with a force of 600 newtons. The force makes a thirty degree angle with the horizon and the trunk weighs 800 newtons. What is the normal force on the trunk. 
     
2 ) Ralph stands on a bathroom scale as his elevator accelerates upward at 0.75 g's. His mass = 100 kg. What does the scale read. Assume the scale uses units of newtons. 
     
3 ) A mass of 2m is attached to the rope on one side of a pulley. A mass of 5m is attached to the other side. Find the magnitude of acceleration for each mass when the mass are released. 
     
4 ) Alfred suspects a problem and decides to measure gravity using an Atwood machine. He uses a mass of 4m on one side of the pulley and 2m on the other. This yields an acceleration of 5 m/s/s. What is the value of g? 
     
5 ) A buzzard has a mass = 2 kg. He lands on a magical wire with no mass stretched horizontally between poles 150 meters apart. Murphy lands exactly half way between the two poles. The wire sags 2 cm. What is the tension in the wire?
     
6 ) Bob pushes Martha on a swing. Draw a free body diagram when the swing's ropes makes an angle of theta with a vertical line and Bob gives Martha a push.
