To find the speed of the specified tram on the rounding, we will use the formula: ac = V ^ 2 / R, whence V = √ (R * ac).
Variables: R – radius of curvature (R = 49 m); ac – centripetal (normal) acceleration (ac = 1 m / s2).
Calculation: V = √ (R * ac) = √ (49 * 1) = 7 m / s.
Answer: At the rounding, the tram moved at a linear speed of 7 m / s.
