Given: The intial position of the ball is 3.4 cm. The final position of the ball is -4.2 cm. The time interval is t = 3 s to t2 = 6.1 s. Step 2 Calculation: The average velocity of the object is equal to the ratio of total displacement and total time taken by the object. Write the expression for the average velocity of the ball. Ax レニ At X2-X1 %3D なー」 Here, v is the average velocity, Ax is the change in position, and At is the time interval. Substitute, all known values in the above expression. -4.2 cm-3.4 cm Vニ 6.1 s-3.0 s -7.6 3.1 =-2.4516 cm/s Thus, the average velocity of the ball is -2.4516 cm/s.
