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?

Respuesta :

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.

  • At a constant velocity, the acceleration of the car will be zero
  • If the acceleration is constant, then the change in velocity occurs at a constant rate or equal time interval.
  • As the change in velocity increases, the acceleration of the car will increase as well.

The acceleration of the race car is calculated as follows;

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

Thus, the acceleration of the race car at the given velocities and time interval is 6 m/s²
