CBSE - Motion

The ratio of the heights from which two bodies are dropped is 3:5 respectively. The ratio of their final velocities is: (1) 9 : 25 (2) √ 3 : √ 5 (3) 5 : 3 (4) √5 : √3

The speed-time graph for a particle moving at constant speed is a straight-line ________ to the time axis. (1) perpendicular (2) parallel (3) inclined (4) aligned

The equations of motion can be derived by using: (1) Distance– time graph (2 Velocity – time graph for non-uniform acceleration (3) Displacement time graph (4) Velocity – time graph for uniform acceleration
