Answer:
10 kg
Explanation:
Assuming a frictionless surface, then force F=ma where F is the applied force, m is the mass and a is acceleration. Making m the subject of the formula then [tex]m=\frac {F}{a}[/tex]
Substituting 100 N for the applied force F and 10 m/s^2 for acceleration a then the value of m will be [tex]m=\frac {100}{10}=10\ kgs[/tex]
Therefore, in terms of kilograms, the bookshelf weighs 10 Kg
