Students were enquired to answer a question at schools and to indicate what is most important for them to succeed. A lot of reactions, one which that stood out was practice. People who usually are successful do not become successful by being born. They work hard and commitment their lives to succeeding. If you want to achieve your goals, keep this in mind! Below some question and answer examples that you could simply make use of to further enhance your knowledge and gain insight that will guide you to continue your school studies.

## Question:

A motorcycle has a mass of 250kg. It goes around a 13.7 m radius turn at 96.5 km/hr. What is the centripetal force?a. 2.95×10^3 Nb. 4.31×10^4Nc. 1.31×10^4 Nd. 719N

## Answer:

The **centripetal force** of a **motorcycle** that has a **mass** of 250kg and goes around a 13.7 m **radius** turn at 96.5 km/hr is **1.31 × 10⁴N**

HOW TO CALCULATE **CENTRIPETAL** **FORCE**:

- The
**centripetal force**can be calculated by using the following formula:

**F**=**mv²/r**

Where;

- F =
**centripetal force**(N) - m =
**mass**of the object (kg) - v =
**velocity**(m/s) - r =
**radius**(m)

- According to this question, a
**motorcycle**has a**mass**of 250kg. It goes around a 13.7 m**radius**turn at 96.5 km/hr.

- First, we need to convert 96.5km/hr to m/s as follows:
- = 96.5km ×1000/1hr × 3600
- = 96,500/3,600
- v = 26.8m/s

- F = (250 × 26.8²) ÷ 13.7

- F = 179560 ÷ 13.7

- F = 13,106.6N

- F = 1.31 × 10⁴N

- Therefore, the
**centripetal force**of a**motorcycle**that has a**mass**of**250kg**and goes around a 13.7 m**radius**turn at 96.5 km/hr is**1.31**×**10⁴N**.

They can hopefully guide the student answer the question by make use of the questions and answer examples. Then may possibly carry out some sharing in a group discussion and also study with the classmate relating to the topic, so another student also obtain some enlightenment and still keeps up the school learning.
