A race car starts from rest on a circular track of radius 293 m. The car's speed increases at the constant rate of 0.800 m/s2. At the point where the magnitudes of the centripetal and tangential accelerations are equal, find the following.
(a) the speed of the race car
(b) the distance traveled
(c) the elapsed time
R = 293 m, Tangential acceleration, A = 0.8 m/s^2.
Angular acceleration = alpha = A/R = 0.8/293 = 2.73 x 10^ -3 ...
The expert examines the magnitudes of a centripetal of a car. The speed, distance traveled and elapsed time is determined. Complete, neat and step-by-step solutions are provided.
