Question

you push a 24 kg box horizontally across a warehouse floor with 66 N of applied force. There is 45 N of friction acting on the sled. Determine the acceleration of the sled in metres per second squared. Enter only the number, rounded to two significant digits. *

Answer 1

The net force applied to the box

$$F_{\rm net}=66-45=21\:\rm N.$$

The acceleration of the box

$$a=\frac{F_{\rm net}}{m}=\frac{21}{24}=0.88\:\rm m/s^2.$$
