Amotorcycle accelerates from 10. m/s to 25 m/s in 5.0 seconds. what is the average acceleration of the bike?
a. 3.0 m/s/s
b. 5.0 m/s/s
c. 15 m/s/s
d. 25 m/s/s

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.

Explanation: Option (A) is the correct answer.

The data is given as follows.

Initial velocity = 10 m/s, final velocity = 25 m/s.

Initial time = 0 seconds, final time = 5 seconds.

The formula to calculate average acceleration is as follows.

       Average acceleration =

                                            =

                                            =

                                            = 3 m/s/s

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

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
