In the figure shown , a person wants to raise a block lying on the ground to a height h . In which case he has to exert more force. Assume pulleys and strings are light .

In the figure shown, a person wants to raise a block lying on the ground to a height h. in both the cases if time required is same then in which case he has to exert more force. Assume pulleys and strings light.

In fig., a person wants to rise a block lying on the ground to a height h. In both the cases, if the time required is same, then in which case he has to exert more force? Assuem pulleys and strigns light.

The block has to be raised to a height L in the same time t. In which case force required is more ?

The pulley shown in figure has a moment of inertia I about it's axis and its radius is R. Find the magnitude of the acceleration of the two blocks. Assume that the string is light and does not slip on the pulley.

Figure shows a block A constrained to slide along the inclined plane of the wedge B shown. Block A is attached with a string which passes through three ideal pulleys and connected to the wedge B. If wedge is pulled toward right with an acceleration a, find (a) the acceleration of the block with respect to wedge (b) the acceleration of the block with respect to ground.

The system starts from rest and A attains a velocity of 5m//s after it has moved 5m toward right. Assuming the arrangement to be frictionless everywhere and pulley and string to be light, the value of the constant force F applied on A is:

Three blocks of masses m_(1), m_(2) and M are arranged as shown in figure. All the surfaces are fricationless and string is inextensible. Pulleys are light. A constant force F is applied on block of mass m_(1) . Pulleys and string are light. Part of the string connecting both pulleys is vertical and part of the strings connecting pulleys with masses m_(1) and m_(2) are horizontal. {:((P),"Accleration of mass " m_(1),(1) F/(m_(1))),((Q),"Acceleration of mass" m_(2),(2) F/(m_(1)+m_(2))),((R),"Acceleration of mass M",(3) "zero"),((S), "Tension in the string",(4) (m_(2)F)/(m_(1)+m_(2))):}

In the given arrangement, mass of the block is M and the surface on which the block is placed is smooth. Assuming all pulleys to be massless and frictionless, strings to be inelastic and light, R_1 , R_2 and R_3 to be light supporting rods, then acceleration of point P will be (A is fixed):

A 1kg block 'B' rests as shown on a bracket 'A' of same mass. Constant forces F_(1)=20N and F_(2)=8N start to act at time t=0 when the distance of block B from pulley is 50cm . Time when block B reaches the pulley is …………………… . ( Assume that friction is absent every where. Pulley and string are light.
