Why is the pressure on the ground more when a man is walking than when he is standing?

A flag leaning to wards the east is inclined at an angle theta to the ground. A man walks a distance of 4 m from the foot of the flag towards the west and the observes the angle of elevation of the top of the flag to be 45^(@) . If, on walking a further distance of 3 m in the same direction, the angle of elevation decreases by 15^(@), tan theta is equal to

A block of mass m and length l is kept at rest on a rough horizontal ground of friction coefficient mu_(k) . A man of mass m is standing at the right end. Now the man starts walking towards left and reaches the left end within time ‘t’. During this time, the displacement of the block is : (Assume the pressing force between the block and the ground remains constant and its value is same as it was initially. Also as sume that the block slides during the entire time (t))

A student (m = 63 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of 0.010 s. The average force exerted on him by the ground is +18,000 N, where the upward direction is taken to be the positive direction. From what height did the student fall ? Assume that the only force acting on him during the collision is that due to the ground.

A block of mass M is tied to one end of a massless rope the other end of the rope is in the hands of a man of mass 2M as shown in the figure the block and the man are resting on a rough plank of mass M as shown in the figure the whole system is resting on a smooth horizontal surface the man pulls the rope pulley is massless and friction what is the displacement of the plank when the block meets the pulley ( Man does not leave his position on plank during the pull)
