Measure your Speed

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

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

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

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.

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.

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.

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.

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.

Scalar quantities in physics are quantities that have only magnitude, while vector quantities have both magnitude and direction.

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}.

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}.

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}.

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}.

The final time is $2.46 \text{ s}$, as it starts from a standstill.

The acceleration due to gravity is approximately $9.8 \text{ m/s}^2$, or $32.2 \text{ ft/s}^2$.
