Question

A 32.0 kg cart is at rest on a frictionless, horizontal surface. The cart experiences an unbalanced force, causing the cart toaccelerate at a rate of +5 m/s?.1. Calculate the magnitude of the net force acting on the cart.A. 0.0 NB. 32.0NC. 160 ND. 314N

Answer 1

Given data

*The given mass of the cart is m = 32.0 kg

*The given acceleration of the cart is

`a=5m/s^2`

The formula for the magnitude of the net force acting on the object is given as

`F_{net_{}}=ma`

Substitute the known values in the above expression as

`\begin{gathered} F_{net_{}}=(32.0)(5) \\ =160.0\text{ N} \end{gathered}`

Thus, the magnitude of the net force acting on the cart is 160.0 N and the correct option is (B)
