Question

A vertical pole standing against a wall topples to the ground. The center of the pole has a speed of 10 m/s as it hits. With what speed does the far end of the pole hit the ground?​

Answer 1

20

Step-by-step explanation:

v = rw

Let base be ground so till centre = r/2 and to other end = r
r is distance between centre and end
v = r/2 * w = 10

omega = 20/r

Now linear velocity at end point = distance to end point * w

r' * w = r * 20/r = 20 m/s
