Answer:
0.5 second
Explanation:
We are given that
Force, F=20 N
Mass, m=5 kg
Change in velocity,=2m/s
We have to find the time taken to change the velocity .
We know that
Force, F=ma
Where
Acceleration, a=Change in velocity/time
[tex]a=\frac{2}{t}[/tex]
Substitute the values
[tex]20=5\times \frac{2}{t}[/tex]
[tex]t=\frac{5\times 2}{20}[/tex]
[tex]t=0.5 s[/tex]
