The string will become taut when the particle will fall through a distance `2 m` in downward direction. So the required impulse `J="mu"=1xxsqrt(2xx10x2)=sqrt(40) kg m//s`
A particle of mass 1 kg is attached to a string of length 5 m . The string is attached to a fixed point O . It is released from theposition as shown in Fig. Calculate a. the impulse developed in the string when it becorries taut, b. the velocity of the particle just after the string becomes taut, c. the impulse developed in this string PQ at this instant.
Two massless string of length 5 m hang from the ceiling very near to each other as shown in the figure. Two balls A and B of masses 0.25kg and 0.5kg are attached to the string. The ball A is released from rest at a height 0.45m as shown in the figure. The collision between two balls is completely elastic. Immediately after the collision, the kinetic energy of ball B is 1 J The velocity of ball A just after the collision is
A rigid ball of mass m strikes a rigid wall at 60^(@) and gets reflected without loss of speed as shown in the figure. The value of impulse imparted by the wll on the ball will be
Calculate the tension in the string shown in figure. The pulley and the string are light and all surfaces are frictionless. Take g=10 m/ s^2 .
Two block A and B of masses 3m and m respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of A and B immediately after the string is cut, are resectively
A ball is projected from a point O as shown in figure it will strike the ground after (g = 10 m/ s^(2) )
A ball of mass m=1kg strikes a smooth horizontal floor as shown in figure. The impulse exerted on the floor is
A small ball of mass m is connected by an inextensible massless string of length with an another ball of mass M = 4m . They are released with zero tension in the string from a height h as shown in the figure. Find the time when the string becomes taut for the first time after the mass M collides with the ground. Take all collisions to be elastic.
Two unequal masses of 1 kg and 2 kg are attached at the two ends of a light inextensible string passing over a smooth pulley as shown in figure. If the system is released from rest, find the work done by string on both the blocks in 1 s. (Take g = 10 ms^(-2) )
Two block of mass 4 kg and 2 kg are attached by an inextensible light string as shown in figure. Both the blocks are pulled vertically upwards by a force F=120N Find (a) the acceleration of the blocks, (b) tension in the string. (Take g= 10 ms^(-2) )
