Question
a book has a mass of 50 kg and an acceleration of 5 m/s2. what is the force on the book?
Final Answer
We will use the formula (F = ma) to obtain the force (F = ma = 50 x 5 = 250N) on the book as 250 Newtons which is our final answer.
Explanation
Data: The information revealed in the question that will help us solve the problem
Mass of the book, m = 50 kg
Acceleration of the book, a = 5 m/s2
Unknown: What we need to find
The force on the book, F = ?
Formula: The equation we need to solve the problem
We need to apply the equation of the Newton’s second law to solve this problem
F = ma
Solution
We will need to substitute our formula with the data to obtain
F = ma = 50 x 5 = 250 N
Therefore, the force on the book is 250 Newton. You will also need to remember that the si unit of force is in Newton.
