What will be the acceleration of a toy cart with a mass of 8 kg. on a frictionless tabletop, if a forceof 5N acts on it to the right and another force of 4N to the left?

Sagot :

Given: F1=5N
          F2=-4N
          m=8kg
F1 is to the right(+), F2  to the left(-)
F=F1+F2
  =5+(-4)=1
therefore, F=m/a
a=F/m
  =8kg/1N
  =8kg=8000g

Credits to Queenz..answer is 8 but the unit sholud me m/s

so acceleration is 8 meter per second
