In 1992 maurizio damilano ,of italy walked 29752m in 2.00h( a) calcula damilano's average in m/s. suppose damilano slows down to 3.00m/s at the midpoint in this journey but then picks up the pace and accelerate to the speed calculated in (a).it takes damilano 30.0 s to accelerate .find the magnitude of the average acceleration during this time interval

Answers:

a)

b)

Explanation:

a) Average velocity is expressed by the following equation:

Where:

is Maurizio's displacement

is the time

Hence:

b) Average acceleration is the variation of velocity over a specified period of time :

Where:

being the initial velocity and the final velocity
