Answer:

5m/s²

Step-by-step explanation:

Given :-

  • Initial Velocity = 40m/s
  • Final velocity = 60 m/s
  • Time = 4s

To Find :-

  • The acceleration .

Solution :-

We know that the rate of change of velocity is called acceleration. Therefore ,

[tex]\sf\implies a = v - u / t \\ [/tex]

[tex]\sf\implies a = 60m/s - 40m/s/ 4 \\ [/tex]

[tex]\sf\implies a = 20m/s \div 4 \\[/tex]

[tex]\bf\implies a = 5m/s^2[/tex]
