In the situation given, all surfaces are frictionless. Pulley is ideal and string is light if F=mg//2 the acceleration of the big block is g//x then x is:

In the situation given all surfaces are frictionless, pulley is ideal and string is light. If F=Mg//2 , find the acceleration of both the block in vector form.

A smooth block of mass m is connected with a spring of stiffness k(=20Nm^(-1) )and natural length l_(0)=0.25 m . If the block is pulled such that the new length of the spring becomes l=0.3m , find the acceleration of the block at the moment when it is released from given positon.

A chain of length L is supported at one end and is hanging vertically when it is released. All of the chain falls freely with acceleration g. The moment, the chain is released a ball is projected up with speed u from a point 2 L below the point of support. Find the interval of time in which the ball will cross through the entire chain.

A uniform chain of length 2L is hanging in equilibrium position, if end B is given a slightly downward displacement the imbalance causes an acceleration. Here pulley is small and smooth & string is inextensible The acceleration of end B when it has been displaced by distance x, is

The time period of a simple pendulum is 4 s and the acceleration due to gravity at the given place is 9.8 ms ^(-2) . Write the following steps in sequential order to find the length of the pendulum. (A) From the above formula, write the value of l and l=(T^(2).g)/(4pi^(2)) (B) Note the given values of the time period (T) and acceleration due to gravity (g). (C)Write the formula, T = 2pi sqrt(l/g) , where l is the length of the pendulum. (D). Substitute the given data and get the value of l .

A chain (A) of length L is coiled up on the edge of a table. Another identical chain (B) is placed straight on the table as shown. A very small length of both the chains is pushed off the edge and it starts falling under gravity. There is no friction (a) Find the acceleration of the chain B at the instant L_(2) length of it is hanging. Assume no kinks in the chain so that the entire chain moves with same speed. (b) For chain A assume that velocity of each element remains zero until it is jerked into motion with a velocity equal to that of the falling section. Find acceleration of the hanging section at the instant a length l_(0) has slipped off the table and its speed is known to be v_(0) at the instant.
