We cannot entertain multiple question of this type, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

Take upward direction as positive and downward direction as negative. Find time taken to reach highest point which means that v =0. use u = 200m/s a = -9.8m/s2 then using v=u+at solve for t

double the value of t to find the total time.

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
