# An automobile rounds a curve of radius 50.0 m on a flat road.

A latter school question and answer asked over students to mention what they presume is the most important important thing for a student to do if they wanted to hit success. The one that response stood out from the rest was practice. Successful people generally are not born successful; they become successful by just hard work and dedication. If you would like to achieve your goals, keep this in mind! down below are one of the answer and question example that you could possibly implement to practice and boost your knowledge and also give you insights that could help you to sustain your study in school.

## Question:

An automobile rounds a curve of radius 50.0 m on a flat road.

The centripetal acceleration to keep the car on the curve is
3.92 m/s2. What is the speed necessary to keep the car on the
curve?

The speed that is necessary for keeping the car on the curve is 14 m/s.

Given that,

• An automobile rounds a curve of radius 50.0 m on a flat road.
• The centripetal acceleration to keep the car on the curve is  3.92 m/s^2.

Based on the above information, the calculation is as follows:

We know that

Here a denotes the centripetal acceleration.

v denotes the speed.
