What is Motion Problems in Physics about?

1. The time of descent of a particle sliding down a vertical circle is least when the angle θ of the chord making with the vertical is 0 degrees. 2. The average speed of a car travelling the first half of a distance at 30 km/hr and the second half at 50 km/hr is 40 km/hr. 3. The ratio of the distance travelled by a particle sliding down a frictionless inclined plane from time t=n-1 seconds to t=n seconds (Sn) to the distance in the next time interval (Sn+1) is given by the expression 2n-1/2n+1.
