Questions and Answers

What is the formula for velocity?

The formula for velocity is $v = \frac{xf - xi}{tf - ti}$.

What is the formula for acceleration?

The formula for acceleration is $a = \frac{vf - vi}{tf - ti}$.

What is the acceleration due to gravity?

The acceleration due to gravity is $-9.8$ meters per second squared.

What is the definition of velocity?

The definition of velocity is simply change in x over the change in t, where x is its position and t is equal to the time. Signup and view all the answers

What is the formula for calculating velocity?

The formula for calculating velocity is delta x over delta t, where delta x represents the change in position and delta t represents the change in time. Signup and view all the answers

How would you calculate Usain Bolt's velocity in the 100 meter dash?

To calculate Usain Bolt's velocity in the 100 meter dash, you would use the formula delta x over delta t, where delta x is 100 meters and delta t is 9.58 seconds. Signup and view all the answers

What is the difference between speed and velocity?

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that refers to both the speed and direction of an object's motion. Signup and view all the answers

What is the cheat that Mr. Andersen mentions for converting meters per second to miles per hour?

In the back of his head, Mr. Andersen converts meters per second to miles per hour by using the approximate conversion of 1 meter per second equals 2.2 miles per hour. Signup and view all the answers

What are scalar and vector quantities in physics?

Scalar quantities in physics are quantities that have only magnitude, while vector quantities have both magnitude and direction. Signup and view all the answers

What is the formula for acceleration?

Acceleration is defined as the change in velocity over the change in time, so the formula is $a = \frac{v_f - v_i}{t_f - t_i}. Signup and view all the answers

What is the formula to convert miles per hour to meters per second?

To convert miles per hour to meters per second, you divide the value in miles per hour by 2.237, so the formula is $v_{\text{m/s}} = \frac{v_{\text{mph}}}{2.237}. Signup and view all the answers

What is the acceleration of the Bugatti Veyron from 0 to 60 miles per hour in 2.46 seconds?

The acceleration is calculated using the formula $a = \frac{v_f - v_i}{t_f - t_i}$, where $v_f = 60 \text{ mph}$, $v_i = 0 \text{ mph}$, $t_f = 2.46 \text{ s}$, and $t_i = 0 \text{ s}$. Therefore, $a = \frac{60 - 0}{2.46 - 0} = 24.39 \text{ mph/s}. Signup and view all the answers

What is the final velocity of the Bugatti Veyron when it goes from 0 to 60 miles per hour in 2.46 seconds?

The final velocity is $60 \text{ mph}$, which needs to be converted to meters per second. Using the conversion formula $v_{\text{m/s}} = \frac{v_{\text{mph}}}{2.237}$, the final velocity is $26.86 \text{ m/s}. Signup and view all the answers

What is the final time it takes for the Bugatti Veyron to go from 0 to 60 miles per hour in 2.46 seconds?

The final time is $2.46 \text{ s}$, as it starts from a standstill. Signup and view all the answers

What is the acceleration due to gravity?

The acceleration due to gravity is approximately $9.8 \text{ m/s}^2$, or $32.2 \text{ ft/s}^2$. Signup and view all the answers
