A car accelerates from 5 m/s to 27 m/s in 10 seconds. What is the acceleration in m/s2 ?

2.2m/s²

Explanation:

Given parameters:

Initial velocity  = 5m/s

Final velocity  = 27m/s

Time  = 10s

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of velocity with time;

 It is mathematically expressed as;

      A  =

v is the final velocity

u is the initial velocity

t is the time taken

Insert the parameters and solve;

    A =   = 2.2m/s²
