In the figure calculate velocity of the block B if block A has a velocity of 4m/s
1 Answer
Devansh Kaushik
In the figure, the block A is having a velocity of 4m/s. There is no relation between the lower block and friction. The string makes an angle 37° with the horizontal. Thus the velocity of the Block B will be breakdown into its components i.e. sine component and cosine component. The cosine component will act along horizontal direction. Therefor the horizontal velocity of the block will be v(horizontal) = v cos37° = 4 x 0.765 = 3.06 ~ 3m/s

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
