Given data
*The given mass of the cart is m = 32.0 kg
*The given acceleration of the cart is
[tex]a=5m/s^2[/tex]The formula for the magnitude of the net force acting on the object is given as
[tex]F_{net_{}}=ma[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} F_{net_{}}=(32.0)(5) \\ =160.0\text{ N} \end{gathered}[/tex]Thus, the magnitude of the net force acting on the cart is 160.0 N and the correct option is (B)
