Answer:
Time, t = 10 seconds.
Explanation:
Given the following data;
Initial velocity, u = 10 m/s
Final velocity, v = 30 m/s
Acceleration, a = 2 m/s²
To find the time, we would use the first equation of motion;
[tex] v = u + at[/tex]
Where;
Making time, t the subject of formula, we have;
[tex] t = \frac{v - u}{a}[/tex]
Substituting into the equation, we have;
[tex] t = \frac{30 - 10}{2}[/tex]
[tex] t = \frac{20}{2}[/tex]
Time, t = 10 seconds.
