WebFind (a) the speed of the train (b) the time it will take to cross a bridge 500m long. Answer 1: (a) 20 m/s. (b) 30 s. Question 2: A car accelerates uniformly from 18 km/h to 36 km h/ in 5 second. Calculate (i) the acceleration and (ii) the distance covered by the car in that time. Answer 2: 1 m/s² ; 37∙5 m. WebHence, car B is the slowest. Question 9: Answer: (a) For uniform motion, the distance-time graph is a straight line (because in uniform motion object covers equal distance in equal interval of time). Question 10: Slope of a velocity-time graph gives. (a) the distance (b) the displacement. (c) the acceleration (d) the speed.

WebQ. A driver of a car travelling at 52km/hr applies brakes and accelerates uniformly in the opposite direction the car stops in 5 seconds. Another driver going at 34km/hr in another car applies brakes slowly and stops in 10 seconds. Plot the speed versus time graph for both time graphs for two cars.
