Step-by-step explanation:
Three blocks of masses 3 kg, 2 kg and 1 kg are placed side by side in contact with each other on a smooth horizontal surface with the 3 kg block on the left extreme and 1 kg block on the right extreme. A horizontal force of 12 N is applied on the 3 kg block pushing it towards the 2 kg block, the contact force between the 2 kg block and 1 kg block is
Q2
Two concrete rectangular blocks 1 and 2 have dimensions as shown in figure. Standing on one of its faces as shown, the pressure exerted by block 1 is P. Both the blocks are made of same material.
What is the pressure exerted by block 2 when it stands on the face as shown in figure?
Q3
The length of a ballistic pendulum is 1m and mass of its block is 1.9kg. A bullet of mass 0.1kg strikes the block of ballistic pendulum in horizontal direction with a velocity 100ms
–1
and got embedded in the block. After collision the combined mass (block & bullet) swings away from lowest point. The tension in the string when it makes an angle 60° with vertical is (g=10ms
