Two forces are applied to a 2.0-kilogram ball on a frictionless, horizontal surface, as shown in the diagram.

2kg
F2=8.0 N
F1=2.0 N
Both arrows point right

The acceleration of the ball is
A) 0
B) 5.0 m/s2 to the right
C) 4.0 m/s2 to the right
D) 1.0 m/s2 to the left
E) 3.0 m/s2 to the left​

Respuesta :

Its B because
Sf=m*a
8.0+2.0=2a (because both arrows point right)
2a=10.0
a=5.0 m/s2
