Suppose a treadmill has an average accelera- tion of 0.0039 m/s2. how much does its speed change after 4.1 min? answer in units of m/s.

Speed change = (final speed) - (initial speed)

Final speed = (initial speed) + (acceleration) x (time)

So Speed change = (acceleration) x (time)

(4.1 min) x (60 sec /min) = 246 seconds

Speed change = (0.0039 m/s²) x (246 seconds)

Speed change = 0.96  m/s

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
