Question

9. A motorcycle accelerates from 10. m/s to 55. m/s in 5.0 seconds. What is the average acceleration of the bike (provide reason)
09.0 m/s/s
O 3.0 m/s/s
O 5 m/s/s
O 11 m/s/s

Answer 1

Answer:

9.0 m/s/s

Explanation:

Given the following data;

Initial velocity = 10 m/s

Final velocity = 55 m/s

Time = 5 seconds

To find the average acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

$Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}$

Substituting into the equation;

$a = \frac{55 - 10}{5}$

$a = \frac{45}{5}$

Acceleration, a = 9.0 m/s²

Therefore, the average acceleration of the motorcycle is 9 meters per seconds square because it's experiencing a uniform velocity or motion.
