* Activity 1.31   :   Working out forces.                                               ( 10/18/17   Wednesday )

1.31.a   Look the following web up :    Work out the following forces.       ( 5 points ).
( Check the example done ).

1.31.b   Now work out the forces at the following data table.        ( 10  points ).

Use your chromebook to creat a table in which you work out
the value of the forces, acceleratios or masses asked.

1.31.c   A truck has a mass of 15,000 kg. The driving force created  by the engine
is 21,000 N. Calculate the acceleration caused by this force.   ( 5 points ).

( You have the solutions there to check).

* Activity 1.32   :   Gravity and weight.                                                    ( 10/19/17   Thursday )

*   These are the questions to answer  looking up the following links :

1.32.a   GRAVITY, MASS AND WEIGHT.
