Calculate the acceleration of a bus full speed changes from 6 miles to 12 miles over a period of three seconds

0.90m/s²

Explanation:

Given parameters:

Initial speed  = 6miles/hr

Final speed  = 12miles/hr

Time taken = 3 seconds

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time. It is mathematically given as:

         Acceleration  =

We need to convert miles/hr to meters/seconds

Initial speed = 6 x x  x

                      = 2.68m/s

Final speed = 12 x  = 5.37m/s

      Acceleration  =   = 0.90m/s²

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
