| The car moves uniformly on a bend along a circular path with a radius of 50 m with a constant modulus speed of 54 km / h. What is the acceleration of a car?
These tasks: the car moves evenly and along a circular path; R (trajectory radius) = 50 m; V (constant vehicle speed module) = 54 km / h (15 m / s).
The acceleration of the car in question can be calculated by the formula: a = √ (an² + aτ²) = √ (an² + 0²) = an = V² / R; aτ (tangential acceleration) = 0 because the vehicle speed is constant.
Calculation: a = 15² / 50 = 4.5 m / s2.
Answer: The acceleration of the vehicle is 4.5 m / s2.
