Explanation / Answer

as two frames per second the ball travells -4 to 0 soi.e 4m in the time interval t= 0s to t=1.0s the travelled from 3 to 7 in the time interval t=2.0s to t=4.0 s i.e 4 m before reaching the sticky section the travelled 4m in onesecond i.e v = 4m / 1 s = 4 m/s ball's velocity after the sticky section is v = 4m / 2s = 2 m/s acceleration = [( 2- 4 ) m/s ] / 1 s                     = - 2 m/s 2 .
