Air Rockets can be a fun way of investigating forces. When a air rocket is launched compressed air
forces the cardboard rocket off the launcher and up into the air.
• Name the forces acting on the rocket at the top of it's flight.
. Are the forces at the top of the flight balenced or unbalenced?
• Describe how the size and direction of the air resistance force changes during flight, an state
the definition of friction.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
