Flash stroboscopic photography, with the help of the continuous flash of electronic flash, records the continuous motion process of moving objects on a picture. As shown in the figure, two objects are transported.
According to the meaning of the question, the time interval of stroboscopic photography is equal, and the time interval between two adjacent photos is t = 0.02 s;
As can be seen from the figure, A has the same distance in equal time, so A moves in a straight line at a constant speed.
As can be seen from the figure, when the distance s is equal, the moving time of A is 5t and that of B is 3t.
Then the ratio of their exercise time T A T B = 5t3t = 53.
The ratio of average speed V A V B = st A st B = t B T A = 3T5t = 35.
So the answer is: uniform straight line; 5:3; 3:5.
