Work Done by Two Forces Acting on an Object

APPHMC-EBXVJY

$F_{A}$ and $F_{B}$ both act on a $0.10 kg$ object, and the object accelerates as a result from $v_{0} = 1 m/s$ to $v_{f} = 2 m/s$.

If $F_{A} = 0.50 N$ and the displacement over which the acceleration happened was $0.20 m$, determine $F_{B}$ .

There were no other forces acting on the object.

A

$-0.15 N$

B

$0.00 N$

C

$0.15 N$

D

$0.25 N$

E

$0.45 N$
