Explanation / Answer

Given :         Two moviersattempt to move a 50 kg crate by pushing in opposite directions.Joe pushes to the right with a force of 1800 N while Jill pushes tothe left with a force of 2000 N. (a)       net force on thecrate is : F2   - F1  = 2000 - 1800 = 200 N (b)       Direction os net force is:   towards left . (c)        We know that F = m a                     a   = F / m   = 200 / 50                                              =    4 m /s2    (d)          direction ofthe acceleration is    towards left Hope this helps u!
