An automobile with an initial speed of 6.12m/s accelerates uniformly at the rate of 4.4 m/s^2.Find the final speed of the car after 4.6 s.
Answer in units of m/s
Does it have any other units in the question as you do not have enough variables to find the final velocity
@Mr.R no sir it does not.
Ok here are your variables
a= 4.4m/s²
Vi= 6.12 m/s
T= 4.6s
You can plug this information into the equation
V= Vi + at
V= 6.12m/s + (4.4m/s²)(4.6s)
This will give you final velocity.
Thank you sooo much!
To find the final speed of the car, we can use the equation of motion:
final speed = initial speed + (acceleration * time)
Given:
Initial speed (u) = 6.12 m/s
Acceleration (a) = 4.4 m/s^2
Time (t) = 4.6 s
Substituting these values into the equation, we get:
final speed = 6.12 m/s + (4.4 m/s^2 * 4.6 s)
To calculate the final speed, we need to multiply the acceleration by the time:
final speed = 6.12 m/s + (20.24 m/s)
Adding the two values together, we get:
final speed = 26.36 m/s
Therefore, the final speed of the car after 4.6 seconds is 26.36 m/s.
