am i doing something wrong?

ok i got the first four parts but the fifth I am still getting wrong... A. a = F/m = 8*9.8 / (10+8) = 4.36 m/s^2 B. 1.1 = (1/2) 4.36 t^2 t = sqrt(2.2/4.36) = 0.711 s C. 4. It moves with a constant acceleration. D. 3. It moves with a constant speed. E. Since the 8 kg block...

Two objects are connected by a string of negligible mass. The 10 kg block is placed on a smooth table top 2.2 m above the floor, and the 8 kg block hangs over the edge of the ta- ble. The 8 kg block is then released from rest at a distance of 1.1 m above the floor at time t = 0. A...
