Given :
The focal length of a concave mirror is 18 cm.
To Find :
The radius of curvature of the concave mirror.
Solution :
We know,
Therefore, the radius of curvature of concave mirror is 36 cm.
Hence, this is the required solution.
A car traveling at 26 m/s starts to decelerate steadily. It comes to a complete stop in 6 seconds. What is its acceleration?
1 answer:
Alright let's start this off with our basic equation!
Accerlation (a) = ?
Initial velocity (V1)= 26 m/s
Final velocity (V2) = 0 ft/s because the car comes to a complete stop!
Time (t) = 6 seconds
The equation for acceleration is below!
a =
So now, just plug in the values!
a =
a =
a = -4.33 m/s²
Therefore, your acceleration is -4.33 m/s²!! Hope this helped and was one of the branliest answers :')
