a bus goes from 25 meters per second to 40 meters per second in 5 seconds. calculate its acceleration. your…

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 25$ m/s, final velocity $v=40$ m/s, time $t = 5$ s.

Step2: Use acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substitute values: $a=\frac{40 - 25}{5}$.

Step3: Calculate acceleration

$a=\frac{15}{5}=3$ m/s².

Answer:

3 m/s²

Brief Explanations:

Speed is a scalar quantity, which only has magnitude (e.g., 50 km/h). Velocity is a vector quantity, which has both magnitude and direction (e.g., 50 km/h north - east).

Answer:

Speed is a scalar (magnitude - only), velocity is a vector (magnitude and direction).
