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.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
