20N weight, so mass must be 20/9.8 kg
F=ma
8=mass*a solve for a.
This ignores friction, which is usually significant.
a horizontal force of 8.0 newtons is used to pull a 20.-newton wooden box moving toward the right along a horizantal, wood surface, as shown.
A. Determine the mass of the box.
B. calculate the magnitude of the acceleration of the box.[Show all work, including the equation and substitution with units.]
