In pulley syste shown in figure, block C is going up at `2(m)/(s)` and block B is going up at `4(m)/(s)`. Find the velocity of block A.

Text Solution

Verified by Experts


`l_1+l_2+l_3=`constant
`i_1+i_2+i_3=0`
`(V-4)+(V-2)+(-2)=0`
`implies2V=8impliesV4(m)/(s)darr`

Figure shows, a system of four pulley with two masses A and B. Find at an instant. (a) Speed of block A when block B is going up at 1ms^(-1) and pulley Y is going up at 2 ms^(-1) . (b) Acceleration of block A if block B is going up 3 ms^(-2) and pulley Y is going down at 1 ms^(-2) .

In the system shown, the block A is moving down eith velocity v_(1) and C is moving up with velocity v_(3) . Express velocity of the block B in terms of velocities of the blocks a and C.

If block A of the pulley system is moving downward with a speed of 1 m//s while block C moving up at 0.5m//s determine the speed of block B

A system is shown in the figure. Block A is moving with 1m//s towards left. Wedge is moving with 1m//s towards right. Then speed of the block B will be :

Two blocks A and B are shown in figure. Block A moves to the left with a constant velocity of 6m/s. Find : (a) Velocity of the blocks B. (b) Velocity of the point P of the string. Relative velocity of the point M of the cable with respect to the point P.

Block C shown in figure-1.79 is going down at acceleration 2 m//s^(2) . Find the acceleration of blocks A and B.

Top view of a block on a table is shown (g = 10 m//s^(2)) Find out the acceleration of the block.

Block C shown in figure, starts from rest and moves downward with a constant acceleration. Knowing that after 12s the velocity of block A 7.2 m/s, determine the acceleration of A, B and C and the velocity and the displacement of block B after 8s.

Block 5 shown in figure moves to the right with a constant velocity of 30 cm/s. Find : (a) The velocity of block A. (b) The velocity of the point P of the string. (c) The velocity of the point M of the string. (d) The relative velocity of the point P of the string with respect to the block A.
