Problem

Three horizontal forces act simultaneously on a cart moving along a straight track. A

1.5\,\text{kN}

force pulls to the right, an

800\,\text{N}

force pulls to the left, and a

0.4\,\text{kN}

force pulls to the right. Determine the net force acting on the cart. (a)

0.7\,\text{kN}

to the right (b)

2.7\,\text{kN}

to the right (c)

1.1\,\text{kN}

to the right (d)

1.1\,\text{kN}

to the left
