Answer:

acceleration:  2.14 m/s²

Explanation:

          acceleration =  (final velocity - initial velocity ) ÷ time taken

Here the final velocity is 16 m/s, initial velocity is 4 m/s, time taken is 5.6 s

acceleration = ( 16 - 4 ) ÷ 5.6

                     → 12 ÷  5.6

                     → [tex]\left[\begin{array}{ccc}\frac{15}{7}\end{array}\right][/tex] m/s² or 2.14 m/s²
