Question

pick correct statements:(multiple choice ) 1. average speed of a particle in a given time is never less then the magnitude of the average velocity 2.it is possible to have a situation in which magnitude of acceleration not equal to 0 but magnitude of †an gential acceleration is equal 3.the average velocity of a particle is 0 in a time interval. it is po.ssible that the ins†an†an eous velocity is never zero in the interval. 4. the average velocity of a particle moving on a straight line is 0 in a time interval.it is possible that ins†an†an eous velocity is never 0 in the interval
