A force f1 acts on a particle
A body sliding on a smooth inclined plane requires 4 sec to reach the bottom after starting from rest at the top. How much time does it take to cover one fourth the distance starting from rest at the top.

Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force F applied on the upper string produces an acceleration of 2m/s2 in the upward direction in both the blocks. If T and T’ be the tensions in the two parts of the string, then:
