6.    The strength of gravity is 10 N/kg on Earth.
                   (a) Calculate the weight of a box which has a mass of 10 kg.
                   (b) Calculate the mass of a truck that has a weight of 35000 N.
              7.       a)  A large rock rests on the
                          ground. The mass of the
                          rock is 800kg. Write
                          down the size of the
                          contact force from the
                          ground.
                       b)  Why is the rock not
                          moving down through
                          the ground?
              8.    Use the informaUon in the diagram of the planets to answer these quesUons.
























                       a)  Give the locaUon where your weight would be greatest.
                       b)  Name the planet where you would have the same weight as on Earth.
                       c)  Calculate the weight of a 25kg mass on Mars.
                       d)  Explain how your mass on Earth would compare with your mass on Mercury
