Question

Using Newtons second law of motion, calculate the acceleration of an object with a mass of 210kg and a force of 2.5N acting on it. Don't forget your units.

Answer 1

`\begin{gathered} Given: \\ mass\text{ of the object=210Kg} \\ Force\text{ acting on it \lparen F\rparen=2.5N} \end{gathered}`
`\begin{gathered} To\text{ find:} \\ a(acceleration)=? \end{gathered}`
`\begin{gathered} form\text{ Newton's second law of motion } \\ F=ma \end{gathered}`
`\begin{gathered} put\text{ the given values in the above formula} \\ 2.5N=210Kg*a \\ a=(2.5N)/(210Kg) \\ a=0.01190\text{m/s}^2 \end{gathered}`

so the acceleration of the object will be 0.01190m/s².
