Question

A meter stick is placed vertically at the origin on a frictionless surface. A gentle push in +x direction is given to the topmost point of the rod when it has fallen completely x coordinate of center of the rod is at:
  1. origin
  2. 0.5 m
  3. 0.75 m
  4. 1 m

A
0.5 m
B
0.75 m
C
origin
D
1 m
Solution
Verified by Toppr

Since there us no external force on the rod, the center of mass of the rod will not move in horizontal direction.
In vertical direction, we have gravitational force as an external force so com of rod will come 0.5m down, but will not move in x direction.
So COM will be the origin.
Thus option A is correct.

Q4
A uniform rod of mass m, length l is placed at rest on a smooth horizontal surface along y axis as shown in figure. An impulsive force F is applied for a very small time interval Δt along x direction at point A. What will be the x coordinate of the end A of the rod when the rod becomes parallel to x axis for the first time? Take origin at the mid point of the rod.

Q5
A uniform rod of mass m, length l is placed over a smooth horizontal surface along y-axis and is at rest as shown in the figure. An impulsive force F is applied, for a small time Δt along x-direction at point A. The x-coordinate of end A of the rod when the rod becomes parallel to x-axis for the first time is (initially the coordinate of center of mass of the rod is (0, 0))
