An   object   is   moving   in   x   direction.   At   t1=3(s)   it   is   located   at   x1=30   (m)   A

An   object   is   moving   in   x   direction.  

At   t1=3(s)   it   is   located   at   x1=30   (m)  

At   t2=5(s)   it   is   located   at   x2   =12   (m)  


  
a)   find   the   velocity   of   the   object.  

b)   what   can   you   tell   about   the   direction   that   the   object   is   moving   to?   Is   it   going   to   (+)   or   (-)?   

c)   find   the   position   equation   (an   equation   that   gives   you   position   of   object   based   on   time)   (hint:   use   the   average   velocity   formula   to   find   it!)
