Question

how much does a bookshelf weigh if the movers are pushing it at a speed of 10 m/s^2 by applying 100 N force

Answer 1

10 kg

Step-by-step 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
`m=\frac {F}{a}`

Substituting 100 N for the applied force F and 10 m/s^2 for acceleration a then the value of m will be
`m=\frac {100}{10}=10\ kgs`

Therefore, in terms of kilograms, the bookshelf weighs 10 Kg
