Answer:
35 m/s
Explanation:
Given that an automobile was moving at 15m/s and accelerated at 2m/s^2 for 10s. what is the final speed ?
The parameters given are :
initial velocity U = 15 m/s
Acceleration a = 2 m/s^2
Time taken = 10s
Using first equation of motion;
V = U + at
V = 15 + 2 * 10
V = 15 + 20
V = 35 m/s
Therefore, The final speed is 35 m/s
The final speed of automobile moving at the given initial speed and acceleration is 35m/s.
Given the data in the question;
- Initial velocity of the automobile; [tex]u = 15m/s[/tex]
- Acceleration of the automobile; [tex]a = 2m/s^2[/tex]
- Time taken; [tex]t = 10s[/tex]
Final velocity of the automobile; [tex]v = ?[/tex]
To determine the final velocity of the automobile, we use the First Equation of Motion:
[tex]v = u + at[/tex]
Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.
We substitute our given values into the equation
[tex]v = 15m/s + [ 2m/s^2 * 10s ]\\\\v = 15m/s + 20m/s\\\\v = 35m/s[/tex]
Therefore, the final speed of automobile moving at the given initial speed and acceleration is 35m/s.
