MCQ
Two pulses having equal and opposite displacements moving in opposite directions overlap at t =t1s. The resultant displacement of the wave at t = t1s is:
  • A
    Twice the displacement of each pulse.
  • B
    Half the displacement of each pulse.
  • C
    Zero.
  • D
    Either (a) or (c).
✓

Answer

  1. Zero.

Explanation:

The displacement due to two pulses will exactly cancel out each other. Thus, there will be no displacement throughout.

A block of mass $1.9\, kg$ is at rest at the edge of a table, of height $1\, m$. A bullet of mass $0.1\, kg$ collides with the block and sticks to it. If the velocity of the bullet is $20\, m / s$ in the horizontal direction just before the collision then the kinetic energy just before the combined system strikes the floor, is $....J$

[Take $g =10\, m / s ^{2}$. Assume there is no rotational motion and loss of energy after the collision is negligable. $]$

One ice skater of mass $m$ moves with speed $2v$ to the right, while another of the same mass $m$ moves with speed $v$ toward the left, as shown in figure $I$. Their paths are separated by $a$ distance $b$. At $t = 0$, when they are both at $x = 0$, they grasp a pole of length $b$ and negligible mass. For $t > 0$, consider the system as a rigid body of two masses $m$ separated by distance $b$, as shown in figure $II$. Which of the following is the correct formula for the motion after $t = 0$ of the skater initially at $y = b/2?$
