Question

A race cars velocity increases from 6.0 m/s to 36 m/s over a 5.0 s time interval. What is It’s average acceleration?

Answer 1

The acceleration of the race car is 6 m/s²

The given parameters;

initial velocity of the race car, u = 6 m/s

final velocity of the race car, v = 36 m/s

time of motion, t = 5 s

Acceleration is defined as the change in velocity per change in time of motion.

The acceleration of the race car is calculated as follows;

$a=\frac{v-u}{t} \\\\a = \frac{36-6}{5} \\\\a = 6 \ m/s^2$

Thus, the acceleration of the race car is 6 m/s²
