Respuesta :

If a motorcycle accelerates from 10 m/s to 15 m/s in 5 seconds, the average acceleration of the bike is 3 m/s/s. This only means that the motorcycle’s velocity will increase 3 m/s every second.  You need to divide 15 m/s which is the difference of 10 and 25 to 5 seconds.

Answer:

Explanation: Option (A) is the correct answer.

The data is given as follows.

Initial velocity [tex](v_{i})[/tex] = 10 m/s, final velocity [tex](v_{f})[/tex] = 25 m/s.

Initial time [tex](t_{i})[/tex] = 0 seconds, final time [tex](v_{t})[/tex] = 5 seconds.

The formula to calculate average acceleration is as follows.

       Average acceleration = [tex]\frac{v_{f} - v_{i}}{t_{f} - t_{i}}[/tex]

                                            = [tex]\frac{(25 - 10)m/s}{(5 - 0)s}[/tex]

                                            = [tex]\frac{15}{5}[/tex]

                                            = 3 m/s/s

Thus, we can conclude that the average acceleration of the bike is 3 m/s/s.
