Class XI The SI unit of retardation is ms-1 ms-2 ms2 m A train moving with a uniform speed of 54 kmph. What is its speed in m/s? 15 m/s 1.5 m/s 9 m/s 90 m/s A truck covers 40 km with an average speed of 80km/h. Then it travels another 40 km with an average speed of 40 km/h. The average speed of the truck for the total distanced covered is 40 km/h 45km/h 48km/h 53km/h Which of the following can determine the acceleration of a moving object? area of velocity-time graph slope of velocity-time graph area of distance-time graph slope of the distance time-graph The equation v = u + at gives information as velocity is a function of time velocity is a function of position Position is a function of time Position is function of velocity and time Do you really want to submit this quiz?
